feat(archive): wire archive converters, validation, and extension parsing into app.js/worker.js

Also fixes a third double-extension bug the plan missed: app.js derived
each job's uuid via path.basename(file.filename, path.extname(...)),
which only strips the last dot segment. For a compound extension like
tar.gz this left "<uuid>.tar" as the "uuid", overflowing the uuid
column (Char(36)) and crashing the request. Replaced with
stripExtension(). Also bumped rateLimitMaxJobs in jobs.test.js's config
override — the file's cumulative POST /api/jobs calls across all tests
now exceeds the production default (20/window) once the archive tests
are included, causing spurious connection resets independent of any
real bug.
