Follow-up to the rename commit: the previous commit moved the files but
the post-mv string substitutions (Go imports, frontend bindings, CI
config paths) were not re-staged so they slipped through. This commit
applies those edits and removes the fyne dependencies from go.mod/go.sum
now that the legacy fyne UI is gone.
Sonar's default scanner picks up TypeScript / JSX from the frontend
tree but applies rules that don't fit a UI codebase reviewed visually
(component dead-code detection, hook-shape conventions, ...). Skip
client/ui-wails/frontend from both analysis and coverage so neither
the rules engine nor the coverage gate trips on UI changes.
The Go side of the Wails UI (client/ui-wails/*.go, services/) is left
in scope on purpose — same Go standards as the rest of the repo.
