fix: Address Pylint issues and bugs in pyUltroid/startup/

- Corrected undefined variable 'x' in funcs.py. - Refactored configuration loading in funcs.py for clarity and to resolve Pylint errors. - Changed logging f-strings to %-style formatting across multiple files. - Added encoding='utf-8' to open() calls. - Replaced list comprehensions used for side-effects with for-loops. - Made some broad exception catches more specific. - Added check=True to subprocess.run() calls in loader.py. - Corrected function signature parameter orders (e.g., *args placement). - Removed some unused variables and imports. - Added Pylint disable comments for known false positives (e.g., no-member for psycopg2.errors and base class methods). - Improved error handling and logging in funcs.py for startup sequences. - Addressed dependency installation issues by commenting out 'pokedex' (unavailable on PyPI) and correcting case for 'SpeechRecognition' in requirements.txt.
