`depName` is a required attribute as per our custom regex.

Currently problematic (leading to failures to start for Synapse) because of:
https://github.com/element-hq/synapse/pull/18759#issuecomment-3172744530

This defaults to true for end user comfort as it helps assure them the modules connection to the consumer is working or is definitively not working. (As far as i have been told it retries until success)

Supersedes https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/4284

This works around an issue with Matrix Authentication Service's `syn2mas` sub-command (at version v0.16.0),
which chokes with an error:

> Error: Failed to load Synapse configuration
> Caused by:
> invalid type: found unit, expected struct EnableableSection for key "default.cas_config" in homeserver.yaml YAML file

This issue is likely to be fixed in MAS v0.16.1 or v0.17.0.

This also reverts e5574a405e because:
- it was causing issues on some servers (not clear why)
- such workarounds are no longer necessary when doing multi-stage building.

This is a security patch for Synapse that fixes an actively exploited bug.

* Enable Internal Admin API Access separately from Public access.

* Add Config variable for Draupnir Hijack command

And also make the internal admin API be automatically  activated when this capability is used.

* Apply suggestions from code review

* Further Refine Internal Admin API

* Add Non Worker Labels for Internal Admin API

* Variable Rename

* Add validation rules for Internal Synapse admin API

* Add Draupnir Admin API required config validation.

* Override `matrix_synapse_reverse_proxy_companion_container_labels_internal_client_synapse_admin_api_traefik_entrypoints` via group vars

* Wire `matrix_bot_draupnir_admin_api_enabled` to `matrix_bot_draupnir_config_admin_enableMakeRoomAdminCommand` in Draupnir's `defaults/main.yml`

* Remove unnecessary `matrix_bot_draupnir_admin_api_enabled` override from `group_vars/matrix_servers`

The same value is now (more appropriately) defined in Draupnir's `defaults/main.yml` file anyway.

* Add additional condition (`matrix_bot_draupnir_enabled`) for enabling `matrix_synapse_container_labels_internal_client_synapse_admin_api_enabled`

* Use a separate task for validating `matrix_bot_draupnir_admin_api_enabled` when `matrix_bot_draupnir_config_admin_enableMakeRoomAdminCommand`

The other task deals with checking for null and not-blank and can't handle booleans properly.
