refactor(verification): move transaction-only verification methods [part 4/5]

[glevco]

Depends on #798

Motivation

This is the fourth PR in a 5-part series of PRs that completely move verification-related code out of the vertex model classes.

This PR moves the verification method implementations of the Transaction inheritance branch.

Acceptance Criteria

• Remove all Transaction and TokenCreationTransaction verification methods from the original model classes, moving the implementation to each respective Verifier class. The only exception is the verify_outputs() method, which is part of the inheritance tree up to BaseTransaction, and will be moved in a separate PR.
• check_authorities_and_deposit() is renamed to verify_authorities_and_deposit(), for consistency.
• update_token_info_from_outputs() is also moved as it's only used by verification.

Checklist

• If you are requesting a merge into master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
