🤖 Bitwarden Claude Code Review

Overall Assessment: APPROVE

This PR drops the v2 suffix from the account recovery command now that the old version was removed with its feature flag. It is a mechanical refactor: files move from AccountRecovery/v2/ into AccountRecovery/, the namespace loses its .v2 segment, the AccountRecoveryV2 alias and _adminRecoverAccountCommandV2 field/parameter are renamed, and DI registrations plus tests are updated in lockstep. I verified there are no remaining references to the old v2 namespace, alias, or field name anywhere in the codebase, and all interface/type references resolve correctly.

Code Review Details

No findings. Clean refactor with consistent rename across source, DI registration, and tests.
