refactor: clean up all code to best readability standards

[kRxZykRxZy]

With a bit of help from OpenCode and github copilot, here is the changlog (its just fixes and cleanups etc and proper async execution)

• fixed sql injection vulnerability in database.py (column whitelist)
• fixed async bug in blockbits.py (get_response called without await)
• fixed ZeroDivisionError in project_commands.py when views is 0
• switched from requests.post to aiohttp in experimental_commands.py
• fixed missing private/ prefix in remove_line_by_index call
• replaced print() with logging across codebase
• replaced type() == with isinstance() for type checks
• renamed shadowed id variables to project_id/studio_id/topic_id
• extracted _extract_project_id/_extract_id helper functions
• add type hints and return annotations throughout
• remove unused imports (scratchattach, time, traceback, etc.)
• use dotenv for token loading instead of reading files
• simplify nested logic in search/user commands
• auto-format all files with ruff

Nice, I see plenty of interesting changes! I also see a few things I'd like to revert before merging, so I'm closing the pull request but keeping the branch open to contribute to it. Thanks for doing this!
