Also adds vitest.config.js with fileParallelism: false. Every DB-backed
test file wipes and reseeds the shared conversion_jobs table in
beforeEach; running test files in parallel (Vitest's default) let one
file's DELETE race another file's just-inserted row against the same
live MariaDB instance, causing intermittent cross-file failures.

Regenerates the sample.png test fixture via sharp itself: the
hand-encoded base64 PNG from the plan had valid magic bytes (enough to
fool file-type's signature check) but was malformed past the header,
which libpng rejected as soon as sharp actually tried to decode it.

Also configures the MariaDB pool with timezone: 'auto', since the
default 'local' mode sends dates without timezone conversion and
silently broke expires_at comparisons whenever the app host and DB
server clocks differ (caught by the findExpiredJobs test).
