* Add dynamic Mikrotik peer support & UI/i18n
Introduce handling for dynamically created Mikrotik peers: add Dynamic/IsDynamic fields to domain, peer and interface models and API models; include "dynamic" in Mikrotik queries; skip updates/deletes for dynamic peers; sync dynamic flag when restoring state. Prevent modifying/deleting dynamic peers in manager. UI: disable selection/edit for dynamic peers and show badge. Implement Mikrotik interface hook execution. Add i18n keys/translations for dynamic-peer messages across languages.
* Fix Mikrotik hooks implementation and UI visibility
