Feature/lit 3140 make pkp base a private instance variable in pkp

[FedericoAmura]

Description

This PR cleans PKPBase authContext and its ex-extending clases PKPEthersWallet, PKPCosmosWallet and PKPSuiWallet. Including changes:

• Removed extension from PKPBase, those classes now implement a shared interface and have a more restricted public interface
• Make litNodeClient a required param in PKP wallets and remove fields to create it, delegating that responsibility to user
• Removed redundant litNodeClient instance inside authContext
• Made PKPBase final (with a private constructor, there is no final in TS)
• Updated PKPClient due to these changes
• Fixed several type definitions
• Updated session sigs demo app to use all PKP wallet classes to test signing

This PR has BREAKING CHANGES due to changes in PKP*Wallet interfaces and removed things (WalletFactory)

Nice! I like that fact that we are passing the pkpBase as an instance now instead of extending it, and also making litNodeClient a required param so we stop fiddling around the default configuration underneath.
