Tighten verbose comments in Wails UI Go code

Shorten over-long godoc/inline comments across the client/ui tray and
services code: drop narrative restatement, legacy-Fyne tangents, and text
already evident from signatures and names. Keep only the non-obvious why
(concurrency/lock ordering, platform quirks, ordering constraints, the
profile-switch state table). No code changes.
