Upload and Replace buffered the entire request body into memory with no
size limit, so a few large uploads could OOM the server. The file
handler now wraps the request body in http.MaxBytesReader and rejects any
file larger than MAX_UPLOAD_BYTES (default 500 MiB) before it is buffered.

Three related auth weaknesses:
- Access and refresh tokens were structurally identical, so a 30-day
refresh token was accepted as a bearer access token. Tokens now carry a
"typ" claim; the access path rejects refresh tokens and /refresh rejects
access tokens.
- Login stored the hash of a throwaway refresh token (sid=0) but returned
a re-issued one, so the stored hash never matched and /refresh always
401'd. Tokens are no longer re-issued: the refresh token is located by
hash and carries no session id, while the access token embeds the real
session id. A random jti keeps tokens unique within the same second.
- Login skipped bcrypt for unknown users (a timing oracle) and returned
403 for blocked accounts before checking the password (leaking account
existence). It now always runs a bcrypt comparison and verifies the
password before disclosing blocked state.

007_seed_data.sql shipped a fixed admin account whose bcrypt hash decodes
to the password "admin", giving every deployment the same known
credentials. The seed row is removed; UserService.EnsureAdmin now creates
the administrator on startup from ADMIN_USERNAME / ADMIN_PASSWORD. It is
idempotent and never overwrites an existing password, so an operator who
rotates the admin password keeps it across restarts.

Two broken-access-control holes:
- PUT/DELETE /files/:id/tags(/:tag_id) and GET /files/:id/tags went
straight to TagService with no ACL check, letting any authenticated
user read or rewrite tags on anyone's private files. The handlers now
require view (list) or edit (mutate) on the target file via new
FileService.AuthorizeView/AuthorizeEdit helpers.
- POST /files/import accepted an arbitrary host path from any user,
turning it into an arbitrary server-side file read. It is now
admin-only and the supplied path is confined to IMPORT_PATH.

GET/PUT /acl/:object_type/:object_id performed no authorization check, so
any authenticated user could read the permission list of, or grant
themselves view/edit on, any file/tag/category/pool. ACLService now
resolves the object's owner and rejects callers who are neither the owner
nor an admin. SetPermissions also wraps its delete+insert replace in a
single transaction so a partial failure can no longer wipe permissions.

Extend PATCH /tags/{id}/rules/{then_id} to accept apply_to_existing bool.
When a rule is activated with apply_to_existing=true, a single recursive
CTE retroactively inserts the full transitive expansion of then_tag into
data.file_tag for all files already carrying when_tag:
WITH RECURSIVE expansion(tag_id) AS (
SELECT then_tag_id
UNION
SELECT r.then_tag_id FROM data.tag_rules r
JOIN expansion e ON r.when_tag_id = e.tag_id
WHERE r.is_active = true
)
INSERT INTO data.file_tag ... ON CONFLICT DO NOTHING
Changes:
- port/repository.go: add applyToExisting param to TagRuleRepo.SetActive
- db/postgres/tag_repo.go: implement recursive CTE retroactive apply
- service/tag_service.go: thread applyToExisting through SetRuleActive
- handler/tag_handler.go: parse apply_to_existing from PATCH body
- openapi.yaml: document apply_to_existing on PATCH endpoint
- integration test: add TestTagRuleActivateApplyToExisting covering
no-op when false, direct+transitive apply when true

- Make data.files.exif column nullable (was NOT NULL but service passes nil
for files without EXIF data, causing a constraint violation on upload)
- FileRepo.Create: include id in INSERT so disk storage path and DB record
share the same UUID (previously DB generated its own UUID, causing a mismatch)
- Integration test: use correct filter DSL format {t=<uuid>} instead of tag:<uuid>

Add internal/integration/server_test.go covering the full happy-path
flow (admin login, user create, upload, tag assign, tag filter, ACL
grant, pool create/add/reorder, trash/restore/permanent-delete, audit
log). Also add targeted tests for blocked-user login prevention, pool
reorder, and tag auto-rules. Uses a disposable postgres:16-alpine
container via testcontainers-go.

Add UserService (GetMe, UpdateMe, admin CRUD with block/unblock),
UserHandler (/users, /users/me), ACLHandler (GET/PUT /acl/:type/:id),
AuditHandler (GET /audit with all filters). Fix UserRepo.Update to
include is_blocked. Wire all remaining routes.

Add pool repo (gap-based position ordering, cursor pagination, add/remove/reorder
files), service, handler, and wire all /pools endpoints including
/pools/:id/files, /pools/:id/files/remove, and /pools/:id/files/reorder.

Add category repo, service, handler, and wire all /categories endpoints
including list, create, get, update, delete, and list-tags.

007_seed_data.sql: insert 10 MIME types (4 image, 6 video) with their
canonical extensions into core.mime_types.
disk.go: register golang.org/x/image/webp decoder so imaging.Open
handles WebP still images. Videos (mp4, mov, avi, webm, 3gp, m4v)
continue to go through the ffmpeg frame-extraction path.

Files stored as {files_path}/{id} (no extension). The ext parameter
is removed from Save/Read/Delete in both the port interface and
the implementation.
Thumbnail and Preview both use imaging.Thumbnail (fit within
configured max bounds, never upscale, never crop) — the config
values THUMB_WIDTH/HEIGHT and PREVIEW_WIDTH/HEIGHT are upper limits,
not forced dimensions.
Non-decodable files (video, etc.) receive a #444455 placeholder.
Cache writes use atomic temp→rename; on cache failure the generated
image is served from memory so the request still succeeds.

filter_parser.go — recursive-descent parser for the {token,...} DSL.
Tokens: t=UUID (tag), m=INT (MIME exact), m~PATTERN (MIME LIKE),
operators & | ! ( ) with standard NOT>AND>OR precedence.
All values go through pgx parameters ($N) — SQL injection impossible.
file_repo.go — full FileRepo:
- Create/GetByID/Update via CTE RETURNING with JOIN for one round-trip
- SoftDelete/Restore/DeletePermanent with RowsAffected guards
- SetTags: full replace (DELETE + INSERT per tag)
- ListTags: delegates to loadTagsBatch (single query for N files)
- List: keyset cursor pagination (bidirectional), anchor mode,
filter DSL, search ILIKE, trash flag, 4 sort columns.
Cursor is base64url(JSON) encoding sort position; backward
pagination fetches in reversed ORDER BY then reverses the slice.

AuditRepo.Log resolves action_type_id/object_type_id via SQL subqueries.
AuditRepo.List supports dynamic filtering by user, action, object type/ID,
and date range with COUNT(*) OVER() for total count.
AuditService.Log reads user from context, marshals details to JSON,
and delegates to the repo.

Add postgres ACLRepo (List/Get/Set) and ACLService with CanView/CanEdit
checks (admin bypass, public flag, creator shortcut, explicit grants)
and GetPermissions/SetPermissions for the /acl endpoints.

Login: bcrypt credential validation, session creation, JWT pair issuance.
Logout/TerminateSession: soft-delete session (is_active = false).
Refresh: token rotation — deactivate old session, issue new pair.
ListSessions: marks IsCurrent by comparing session IDs.
ParseAccessToken: for use by auth middleware.
Claims carry uid (int16), adm (bool), sid (int). Refresh tokens are
stored as SHA-256 hashes; raw tokens never reach the database.

db/db.go: TxFromContext/ContextWithTx for transaction propagation,
Querier interface (QueryRow/Query/Exec), ScanRow generic helper,
ClampLimit/ClampOffset pagination guards.
db/postgres/postgres.go: NewPool with ping validation, Transactor
backed by pgxpool (BeginTx → fn → commit/rollback), connOrTx helper
that returns the active transaction from context or falls back to pool.
