fix(hermes): keep the Gitea admin PAT out of the agent's OpenBao reach; safer hand-over

review-bot on de080442:
- The site-admin PAT moves from apps/hermes/gitea-admin (readable by the agent's
  `hermes` role, homelab/data/apps/hermes/*) to apps/gitea-webhook-sync/admin.
  Only ESO reads it (eso role, existing ClusterSecretStore); `bao token
  capabilities` with the hermes role: deny on the new path. ExternalSecret and
  K8s Secret are now gitea-webhook-sync-admin, mounted only by the CronJob.
- Hand-over writes the expert body before reassigning. If the coordinator claims
  the card in between, its routing body is restored and the expert gets the
  separate @expert card; if the edit fails, nothing is reassigned. Tests for both.
- [alert] cards: a comment is the owner's only by its API user.login (k.renner,
  the login issue-fix trusted and the one commenting on homelab issues), never by
  a name or quote in the text.
- Labels and backfill only in repos where hermes-bot has issue write (per
  /collaborators/hermes-bot/permission), org labels only for orgs owning such a
  repo; gitea_admin/_cargo-index (hermes-bot: read) no longer gets labels.
- Backfill starts no replay after RUN_BUDGET_SECONDS (900); activeDeadlineSeconds
  1200 covers that plus one 60 s delivery; a test pins the relation.

Verified live: Gitea 1.27.3 swagger says IssueLabelsOption.labels takes IDs or
names, so the coordinator's {"labels": ["<expert>"]} works; hermes-bot has
write on konairius/homelab.
