types: add shared DBCursor protocol; annotate special modules and core

- Introduce packages/special/types.py with DBCursor Protocol
- Add/ tighten type hints across special/, sqlcompleter, sqlexecute, clibuffer/toolbar/style, config, filepaths, lexer, completion_refresher, key_bindings
- Remove remaining mypy ignore headers in special modules
- Replace Any with concrete types where safe; improve TextIO handling
- Fix utils.check_if_sqlitedotcommand to handle non-str inputs safely
- Remove mycli references in comments and update docstrings
- Minor refactors for clarity; ruff+mypy clean
