fix: remove orphaned @node-rs/argon2 and restore CI workflow

The hash-wasm package now handles both argon2id and bcrypt hashing,
making @node-rs/argon2 unused. Leaving it in package.json causes
native binary compilation failures on deploy servers (EACCES/build
errors), which breaks the deploy pipeline entirely.

Also restore .gitea/workflows/ci.yaml so CI pipelines run again.
