fix(git): webhook receiver — fork-sync events + missing deployment version (#47)

Two fixes in the push receiver:

- Accept repo-sync events (`sync`, `repository_dispatch`, `workflow_run`)
  that carry no ref — fork-sync bots and Actions dispatch these instead
  of pushes. Branch falls back to the webhook filter then the service's
  own git_branch; repo-only match when no branch is known.
- The deployment INSERT omitted the NOT NULL `version` column, so every
  webhook-triggered deploy failed the insert silently and enqueued
  nothing. Push-triggered deploys have been dead since the receiver
  shipped. Now set `v<unix>` like the manual deploy path.

Verified live: repository_dispatch → branch=main, 1 deployment enqueued;
push → 1; star → ignored.
