feat(precedent-library): auto-trigger CEO wakeup on manual extract requests

The "חלץ מטא-דאטה" / "חלץ הלכות" buttons in the UI used to only stamp
the queue (set metadata_extraction_requested_at / halacha_extraction_requested_at)
and rely on a human running `mcp__legal-ai__precedent_process_pending` from
local Claude Code to drain it.

That left the user with an unintuitive two-step flow: click button → run
local MCP tool. Meanwhile, the upload endpoint already does the right
thing — after ingest succeeds it calls `pc_wake_for_precedent_extraction`,
which creates a Paperclip issue, assigns it to the CEO, and wakes them
to run `precedent_process_pending` automatically.

Add the same wakeup call to the manual request-metadata / request-halachot
endpoints. Now clicking the button is sufficient — the CEO picks it up
and drains the queue without manual intervention.

Best-effort: matches the upload flow's failure semantics. The queue stamp
still happens even if the wakeup fails, so the user can fall back to the
manual MCP tool when needed. The wakeup outcome is included in the
response under `wakeup` for observability.

Coolify deploy required for the FastAPI container to pick this up.
