test(unit): align genai_plugin_load + register plugin_runtime_views

Two unit-test-side fixes uncovered by running unit-tests-g1 against
the new ABI-3 / Phase-B plugin shape:

# genai_plugin_load_unit-t

* setup_admindb_schema was using a pre-Step-4.G shape for the
  mcp_auth_profiles / mcp_target_profiles tables — the new
  install_*_from_admin reads the full canonical column set
  (use_ssl, ssl_mode, comment for auth; description, comment for
  targets) and was failing with `no such column: use_ssl`.  Fixture
  now mirrors the DDL in include/ProxySQL_Admin_Tables_Definitions.h
  and also creates mcp_query_rules + runtime_mcp_query_rules so the
  newly-added install_query_rules_from_admin path also has tables to
  read.

* As of Step 4.G the genai plugin publishes its admin/config/stats
  table set via genai_register_schemas (Phase B), not init.  The
  test was calling load → init_all → start_all and the table-count
  assertions saw zero rows because Phase B never fired.  Add an
  explicit invoke_register_schemas_phase between load and init_all
  (matches the order ProxySQL itself uses at startup) and bump the
  plan from 25 to 26 to cover the new ok().

# Makefile UNIT_TESTS list

plugin_runtime_views_unit-t.cpp lives in test/tap/tests/unit/ and
exercises the chassis ABI-3 register_runtime_view dispatch surface
that landed in PR #5688.  It had a build rule but wasn't in
UNIT_TESTS, so the runner reported "(not-found)" for it.  Wire it
in alongside the other plugin-chassis unit tests under PROXYSQL40.
