jwinterm cf85dce89f privacy: drop raw-IP PII columns and the dead wallets table
The published privacy policy states that IP addresses are retained only as a
salted one-way hash for rate limiting. That was true of the login-event path
but not of sessions.ip_address or audit_logs.ip_address, both of which stored
a raw client IP tied to user_id on every login.

Drop both columns and all writer/model code, so the schema enforces the policy
rather than relying on convention. The hashed rate-limit path (login_events,
restore_attempts) is unchanged and remains the only IP retention.

Also drops the `wallets` table, which was created in the initial schema and
never read or written: a latent user_id -> address / view_key store.

The operator forensic trail (admin_audit_logs, admin_sessions) deliberately
keeps its raw IP. Privileged-action forensics is a different threat model and
is not covered by the user-facing claim.
