Standardized TOS clauses

[zkat]

There should be a standard list of common TOS clauses of interest that a studio can pick from, on top of the full text TOS, that would allow for arbitrary filtering/searching by those clauses.

For example: commercial use, copyright transfer, artist self-promotion/portfolio usage, etc. We can also add to this the "immutable" ones defined at the Banchan level, like the AI ban, the refund policy, the rejection/cancellation policy, etc.

Other thoughts:

• It'd be helpful if the selected standardized clauses were explicitly separated out by UI.
• Show standard commission terms by default? I didn't know that some of those clauses were standard.
• Parameterize commission terms? I.e. **Usage Rights: __Personal__** vs `Usage Rights: Personal, Commercial
• Some artists include "will/won't do" in TOS - this seems like a great attribute to pull out for discoverability.

Operational thoughts:

• When deploying new clauses, it'd be nice if there was UX that encouraged migration to standard clauses.
