fix: stabilize markdown notes — internal link modal, rename UI, trash integration
- Replace broken ObjectPickerModal with simple inline modal (Label+URL fields)
- Insert internal link at cursor position in textarea
- Add rename button in note editor header and note cards
- Add delete button on note cards with confirm dialog
- Integrate DeleteNote with shared trash (.verstak/trash/) via files.TrashFile()
- Remove hidden .verstak/trash/notes/ folder — notes use unified trash now
- Fix purgeTrashNode to clean file-record-based trash entries (notes/files)
- Add activity + sync ops to DeleteNote binding
- Add files.TrashFile() public method
- Update i18n keys for note.rename, note.deleteConfirm, internal link modal
- AssertContained: symlink-aware path containment check
- Update tests: shared trash, file record missing flag, collision on rename
- All go test ./... pass, frontend build passes, GUI binary built
