- The database page's columns, primary keys, FTS tables, hidden flags and
foreign keys come from the _internal catalog (catalog_all_foreign_keys()
added); only row counts query the database. Removes three round trips
per table and the O(tables^2) hidden-table check from that page.
- PaginatedResources.all() fetches everything after the first page in a
single query: each page re-ran the whole permission query, so iterating
87,000 tables cost O(N^2 / 1000) (21 s of the index page at N=5000).
- catalog_generation is bumped after the per-database state it covers.
- Docs: index page row-count behaviour (pages.rst), immutable counts are
computed on first use (performance.rst), catalog_tables.type and "pages
that cover many databases read the catalog" (internals.rst).
