feat: add signer-key to stack-increase event

[hstove]

This does two things:

• Adds max-amount and auth-id to synthetic events for stack-stx, stack-extend, and stack-aggregation-commit

• Adds all the signer key and related args to the synthetic event for stack-increase

• Closes [Nakamoto] Include signer-key (and other args) in stack-increase events #4490

[hstove]

This will conflict with #4414. I'm happy to add this to that PR or the opposite, just lmk @8marz8 @zone117x

Thanks @hstove! This LGTM. I think we should merge it and rebase #4414
