db_name = TNCSC (added in 0f462ad) made Odoo create a new empty TNCSC
database on the server and hide the existing metatrontncsc database,
because db_name both auto-creates a missing database and restricts
which databases are listed and served. Local dev shares this file, so
the line would do the same on every developer's machine.
Also adds HANDOFF-2026-09-28.md (this round's work, deploy steps,
pending work and decisions), links it from HANDOFF.md, and commits
docs/website-link-audit.md.
