fix(ci): install procrastinate in the dev group so ty + unit tests resolve it

CI runs `uv run --frozen ty check -- nextcloud_mcp_server` and `uv run pytest -m
unit`, which install the default + dev groups but not the `[postgres]` optional
extra. vector/queue/procrastinate.py imports procrastinate at module scope (the
task registration needs App/Blueprint), so without it installed ty fails on
unresolved imports and the procrastinate unit tests fail to collect.

Add procrastinate + psycopg to the dev group (kept in the [postgres] extra for
production opt-in) so dev/CI always type-check and test against them, while
SQLite/personal installs stay free of the Postgres deps. Matches the repo's
optional-DB-driver philosophy.
