Add UI inputs for session replay masking settings

[OmG3r]

Background

Currently the app does not offer UI elements to configure session recording masking. so the PostHog JS SDK uses default settings.
this was omitted in the initial development of the app because the settings were unclear and complicated to setup.

Actions

we should implement a setting for:

• session_recording.maskAllInputs (boolean)
• session_recording.maskInputOptions (array of objects of input types with boolean switch)
• session_recording.maskTextSelector (string)

session_recording.maskInputFn and session_recording.maskTextFn will not be implement as they are functions. we cannot serialize function.

there are other controls that are not documented in the public docs and available the source code. might implement some others based on the UX
