Both thumbnails and previews went through imaging.Thumbnail, which scales and
centre-crops to the exact dimensions — so portrait images lost their top and
bottom in the viewer (and the grid). Switch both to imaging.Fit, which scales to
fit within the bounds preserving aspect ratio, never cropping or upscaling. The
grid cell letterboxes the thumbnail via the existing object-fit: contain.
Note: cached *_thumb.jpg / *_preview.jpg are regenerated only when absent, so
clear THUMBS_CACHE_PATH after deploying to drop the old cropped renders.

Run gofmt -w across the backend, normalising the manually-aligned := blocks
to the gofmt standard. No code behaviour changes.
Add Prettier (+ prettier-plugin-svelte) to the frontend with the SvelteKit
default config (tabs, single quotes) so formatting is reproducible, then run
it over the whole tree. Add format / format:check npm scripts and a
.prettierignore (build output, generated schema.ts, static assets).

Replacing a file's content left the old {id}_thumb.jpg / {id}_preview.jpg
in the cache, and the cache-hit fast path kept serving the stale image
forever; permanent deletion left those files orphaned. FileStorage gains
InvalidateCache, which Replace and PermanentDelete now call.

Thumbnail/preview generation decoded untrusted images with no size limit
(a decompression bomb could exhaust memory) and ran ffmpeg with no
timeout (a malformed video could hang the request). Image dimensions are
now checked via image.DecodeConfig before the raster is allocated and
rejected above 64 Mpx, and ffmpeg runs under a 30s timeout.

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.
