feat: add webhook, repo delete/search, admin, pr clean/resolve/review-comments

Second pass of tea-parity work:

- fgj webhook {list,create,update,delete}: full CRUD over repo webhooks.
  Create supports all standard hook types (gitea, slack, discord, etc.),
  event selection, content type, secret, branch filter, auth header.
  Update is partial — flags you omit leave existing config unchanged.
- fgj repo delete: type-to-confirm deletion; --yes skips for scripts;
  refuses without a TTY unless --yes is passed.
- fgj repo search: SDK SearchRepos with query, topic/description,
  private/archived, --type (source/fork/mirror), owner, sort/order.
- fgj admin user list: admin-gated user enumeration.
- fgj pr clean: delete the local branch from 'pr checkout'. Refuses
  if the PR is still open (use --force) or if the branch is currently
  checked out.
- fgj pr review-comments: list inline review comments across every
  review on a PR (ListPullReviews + ListPullReviewComments per review).
- fgj pr resolve / unresolve: mark review comments as (un)resolved.
  Uses raw POST since SDK v0.22.1 predates these endpoints; requires
  Forgejo 8.x+ / Gitea 1.22+ server-side.

All share the standard parseRepo + config.Load + NewClientFromConfig
pattern; list commands support --json / --jq.
