refactor(frontend): rename useOverwriteAction to useOverwrite

Inside `components/shared/overwrite/` the folder name already supplies
context, so the `-action` suffix is redundant — same principle that
turned overwrite-confirm-dialog into overwrite-dialog. Rename file
use-overwrite-action.ts → use-overwrite.ts, export useOverwriteAction
→ useOverwrite, and the internal UseOverwriteAction* prop/result types
to match. The shape lines up with the project's verb-noun action-hook
convention (useResourcesCopy, useResourcesMove).
