Remove custom recovery passphrase flow from FOSS secure backup setup

The custom passphrase entry/confirm UI now lives in the enterprise secure backup module behind the SecureBackupSetupEntryPoint seam. Reverts the setup presenter, view, state, state machine, state provider, and events to the auto-generated-key-only flow, deletes CustomPassphraseDerivations and the temporary strings, and drops the well-known and enterprise-test dependencies the feature required.
