refactor(server): simplify github webhook wiring
- Capture webhook secret at route mount time via Arc<[u8]> router
  state so the handler drops its per-request server_secret lookup
  and the dead NOT_FOUND fallback.
- Extract WEBHOOK_ROUTE and WEBHOOK_SECRET_ENV constants; apply
  across serve.rs, server.rs, and TailscaleFunnelManager so the
  mounted route and the URLs pushed to GitHub cannot drift.
- Flatten the seven-level nested webhook startup match in serve.rs
  into a single start_webhook_strategy helper with early returns,
  short-circuiting when the secret is absent and replacing the
  server.api.url .expect with a propagated error.
- Share compute_signature and a new read_repo_file helper across
  tests; delete the duplicated webhook_signature, TestHmacSha256,
  and read_doc/repo_root copies.
- Replace the nested for-loops in the new webhook auth tests with
  five flat #[tokio::test] cases per CLAUDE.md.

// Note: the earlier `server_settings_keys_match_openapi_spec` drift check
// was deleted in Stage 6.3b alongside the legacy flat `fabro_types::Settings`
// struct that it instantiated. The v2 `/api/v1/settings` and
// `/api/v1/runs/:id/settings` endpoints now return the freely-shaped
// `SettingsLayer` tree which the OpenAPI spec declares as
// `type: object, additionalProperties: true`, so there is nothing to diff
// at the property-key level.
