refactor(webhook): encrypt manual webhook secrets and tighten HMAC verification

- Auto-generate a 40-char random secret for each manual_webhook_secret_* column on Application creation so new apps are never left with an empty secret.
- Add encrypted cast for the four webhook-secret columns; backfill migration re-encrypts existing plaintext values and fills missing ones.
- Reject webhook deliveries when the stored secret is empty (GitHub, GitLab, Bitbucket, Gitea manual endpoints).
- Bitbucket: require the sha256 algorithm prefix on X-Hub-Signature instead of trusting the client-supplied algo.
- GitLab: drop the ?? '' fallback on the token comparison.
