§22.13 step 1: default-project-id re-stamp (v0.39.0)

projects.restamp_default_project(config): at startup after the registry mirror,
renames project_id from the M1 bootstrap 'default' to the configured
DEFAULT_PROJECT_ID across every project-scoped table (discovered by column) and
drops the stale 'default' projects row, so a deployment's original corpus lands
at a meaningful /p/<id>/ and 'default' is never a public URL. FK off for the
rename (parent+children move together) + foreign_key_check backstop. Idempotent;
no-op unless DEFAULT_PROJECT_ID is set to a non-'default' value.

test_restamp_default_project.py (3 tests). 450 backend green.

This is the last framework piece for OHM's clean /p/ohm/ cutover.
