fix: Ignore reader hotkeys in text inputs and with modifier keys

- Skip hotkey handling when user is in INPUT, TEXTAREA, or contentEditable
- Skip hotkey handling when inside settings drawer or popovers
- Skip hotkey handling when inside OCR text boxes (.textBox)
- Ignore letter and nav key shortcuts when any modifier key is pressed
- Allows Ctrl+C, Shift+Arrow, Ctrl+Arrow, etc. to work normally
