feat: add GitHub and GitLab webhook support

Add auto-detection of webhook source (Gitea, GitHub, GitLab) by
examining HTTP headers (X-Gitea-Event, X-GitHub-Event, X-Gitlab-Event).

Parse push webhook payloads from all three platforms into a normalized
PushEvent type for unified processing. Each platform's payload format
is handled by dedicated parser functions with correct field mapping
and commit URL extraction.

The webhook handler now detects the source automatically — existing
Gitea webhooks continue to work unchanged, while GitHub and GitLab
webhooks are parsed with their respective payload formats.

Includes comprehensive tests for source detection, event type
extraction, payload parsing for all three platforms, commit URL
fallback logic, and integration tests via HandleWebhook.

-
-All custom metrics are exposed under the `upaas_` namespace at `/metrics`. The
-endpoint is always available and can be optionally protected with basic auth via
-`METRICS_USERNAME` and `METRICS_PASSWORD`.
-

-### Audit Log
-
-All user-facing actions are recorded in an `audit_log` SQLite table with:
-
-- **Who**: user ID and username
-- **What**: action type and affected resource (app, deployment, session, etc.)
-- **Where**: client IP (via X-Real-IP/X-Forwarded-For/RemoteAddr)
-- **When**: timestamp
-
-Audited actions include login/logout, app CRUD, deployments, container
-start/stop/restart, rollbacks, deployment cancellation, and webhook receipt.
-
-The audit log is available via the API at `GET /api/v1/audit?limit=N` (max 500,
-default 50).
-
-### Structured Logging
-
-All operations use Go's `slog` structured logger. HTTP requests are logged with
-method, URL, status code, response size, latency, user agent, and client IP.
-Deployment events are logged with app name, status, and duration. Audit events
-are also logged to stdout for correlation with external log aggregators.
