fix(profile): use user_role_profile_id column, not id, for profession tables

The profession-specific tables (photographer_profiles, tutor_profiles, etc.)
were extended with a separate user_role_profile_id FK column and a NOT NULL
user_id column, but every generic profile query still treated the shared
user_role_profiles.id value as if it were the profession table's own `id`
PK, and never supplied user_id at all. Result: PATCH /api/profile 500'd
with "null value in column user_id violates not-null constraint" on every
first-time save for any of the 10 professional roles — profile saves were
completely broken, which cascades into submit-for-verification always
running off an empty fallback payload with no real data or documents.
Fixes get_profile, save_profile, set_profile_status, and
fetch_saved_profile_by_urp_id to query/write user_role_profile_id (and
populate user_id on insert) instead of assuming id.
