feat(code): adjust pasted text UX, add explicit shortcut

[adboio]

trying (again) to smooth out the pasted text UX...

• bumps default limit to 1000, adds larger options in settings
• adds new explicit cmd+shift+v shortcut for pasting as a file
  • this is usually the "paste with formatting" shortcut, but i feel comfortable hijacking it since there is no concept for formatting in the inputs here
• adds ability to convert pasted text to inline by clicking the chip
• adds hints to tell you about the click-to-convert and cmd+shift+v keyboard shortcut when you paste things
  • also introduces a very tiny "hint" mechanism so we can show the hints max N times, and stop showing them when we determine the behavior is learned
