Drop leftover trust center page_title columns

[gearnode]

Summary

Organization create fails when trust_centers still has the obsolete NOT NULL page_title (or title) column:

cannot insert organization: cannot insert compliance portal: …
ERROR: null value in column "page_title" … (SQLSTATE 23502)

Inserts only populate entity_name. Branding briefly lived as page_title → title → entity_name; installs that skipped the rename can keep the old NOT NULL column beside entity_name, so new portal rows violate the constraint.

Changes

• Make the page_title → title rename idempotent
• Make the title backfill accept either title or page_title
• Drop both obsolete columns when introducing entity_name
• Add a repair migration that ensures entity_name exists and drops leftover page_title/title

Test plan

• Applied full migration chain on a fresh DB → only entity_name remains
• Simulated stuck schema (page_title + entity_name) → repair drops page_title; insert with entity_name succeeds
• Simulated page_title-only schema → repair adds entity_name from page_title and drops the old column
• Simulated skipped rename, then continued migrations → hardened chain reaches entity_name-only schema
