Cleanup dead code & consolidate remaining contracts

[cpb8010]

There's lots of code as part of the base account and other supporting modules that isn't being used because the entry points have evolved over time. As we're no longer looking to remain backwards compatible, there are lots of places where we can do some clean up.

• Storage layout containing unused lists
• Passkey contracts extending instead of just modifiying
• Auth types
• Hook management being independent from module management (needs to be consolidated as part of a different issue first)
• Upgrade management (old registry)
• Non-module based validation (r1 vs k1 split, related to storage)
