fix: add TrayRecoveryService with bidirectional SNI dedup (Go server) (#2137)

* fix: add TrayRecoveryService with bidirectional SNI dedup (Go server)

Add TrayRecoveryService manager that re-registers lost tray icons after
resume from suspend via native DBus scanning in the Go server.

The service resolves every registered SNI item (both well-known names and
:1.xxx connection IDs) to a canonical connection ID, building a unified
registeredConnIDs set before either scan section runs. This prevents
duplicates in both directions:

- If an app registered via well-known name, the connection-ID section
  skips its :1.xxx entry.
- If an app registered via connection ID, the well-known-name section
  skips its well-known name (checked through registeredConnIDs).
- After successfully registering via well-known name, registeredConnIDs
  is updated immediately so the connection-ID section won't probe the
  same app in the same run.

A startup scan (3 s delay) covers the common case where the DMS process
is killed during suspend and restarted by systemd (Type=dbus), so the
loginctl PrepareForSleep watcher alone is not sufficient. The startup
scan is harmless on a normal boot — it finds all items already registered
and exits early.

Go port of quickshell commit 1470aa3.

* fix: 'interface{}' can be replaced by 'any'

* TrayRecoveryService: Remove objPath parameter from registerSNI
