feat: add file import and prompt() methods for API key entry in OBS

OBS Browser Source lacks clipboard support, making it impractical to
enter long API keys. Add two workarounds: "Import from File" reads a
key from a .txt file via the native file picker, and "Paste Key" uses
window.prompt() where OS-level paste should work.
