feat(routing): add panel-only comment field to routing rules (#6361)

Can annotate rules with a human-readable note for easier management.
The comment is stripped before sending the config to xray-core (same
pattern as the existing 'enabled' flag).

Backend: stripDisabledRules now removes 'comment' from generated config.
Frontend: input field in RuleFormModal, column in desktop table, chip
with tooltip in mobile card list. Schema and type definitions updated.
