fix(mcms): improve error messages when proposal ctx is not correctly provided [OPT-325]

[ecPablo]

This pull request introduces improved error handling and validation for the proposal analysis context and EVM registry initialization across the MCMSv2 CLI and EVM analyzer. These changes help prevent misconfiguration and provide clearer guidance to developers when required dependencies are missing.

Validation and error messaging improvements:

• Added a check in buildMCMSv2AnalyzeProposalCmd to ensure proposalCtxProvider is not nil, returning a descriptive error if missing.
• Enhanced error handling in newCfgv2 to verify that the proposal context returned by the provider is not nil, with a clear error message for initialization issues.

EVM registry initialization guidance:

• Improved the error message in AnalyzeEVMTransaction to instruct developers to provide an EVM registry via the ProposalContextProvider with the WithEVMABIMappings() option if it is missing.
