Fix bulk task instance update for mapped TIs and auth error rendering (#65874)

On v3-2-test, BulkTaskInstanceService had three pre-existing bugs:

1. `_perform_update` did not pass `map_index` to
   `_patch_ti_validate_request`, so the validation step looked up the
   wrong TI (default map_index=-1) and persistence silently no-op'd
   for mapped task instances.

2. `specific_entity_map` and `all_map_entity_map` used raw
   `(entity.dag_id, entity.dag_run_id, entity.task_id, ...)` tuples
   as keys. When `dag_id`/`dag_run_id` came from the path and not the
   request body, those attributes were `None` on the entity, while
   keys produced by `_categorize_entities` resolved them via
   `_extract_task_identifiers`. The resulting key mismatch meant
   matched task keys never resolved back to an entity, so
   `_perform_update` was never called and `response.update.success`
   came back empty.

3. `action_name=action.action` rendered as `'BulkAction.UPDATE'`
   /`'BulkAction.DELETE'` in authorization error messages because
   Python's str-enum `__format__` returns the enum repr, not the
   value. Use `.value` to get "update"/"delete".

All three fixes already exist on main; this backport is the minimal
diff to bring v3-2-test in line with main for this file.

Also includes the following pre-existing v3-2-test fixes that the
prek hooks force to land alongside any source change:

- Regenerated _private_ui.yaml, schemas.gen.ts and types.gen.ts:
  generate-openapi-spec caught a description drift on `ExtraMenuItem`.
- Added `fpr` to docs/spelling_wordlist.txt: codespell flagged the
  GPG colons-format `^fpr:` regex tag in dev/README_RELEASE_*.md.
  Same fix already on main from #65501.
- Regenerated dev/breeze/doc/images/output_pr_auto-triage.{svg,txt}:
  the boring-cyborg config update in #65872 added the
  `backport-to-airflow-ctl-v0-1-test` label, which appears in the
  `breeze pr auto-triage --help` output and changes its hash.
