feat(table): add TABLEDIT point picking, and consolidate InputKind

- Implement `TABLEDIT` command supporting viewport point-picking on cell interiors
- Support overlapping table hit testing with selection cycling and top-table resolution
- Support `/n` and `\n` multiline paragraph breaks (`\P`) in table cell text editing
- Unify text input modes via `InputKind` (`Point`, `SingleToken`, `FreeText`) on `CadCommand`
- Migrate 15+ commands across annotate, draw, insert, layout, and view modules
- Preserve text casing, literal spaces, and bypass arithmetic eval during FreeText input
- Add dedicated `tabledit_tests` and `free_text_entry_tests` test suites
