[PM-7066] Make init_crypto take MasterKey

[dani-garcia]

Type of change

- [ ] Bug fix
- [ ] New feature development
- [x] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
- [ ] Build/deploy pipeline (DevOps)
- [ ] Other

Objective

By making the init_crypto_* functions take MasterKey directly, we remove the need for login_method to be set before the init_crypto call. We also centralize the use of the raw password to the MasterKey::derive function, which allows us to more easily secure it.
