feat: move Smart Locks and ACS sections under Low-Level APIs

Per review, relocate the entire Smart Locks and Access Control Systems
capability sections to a new "Low-Level APIs" group at the bottom of
the nav. Both trees keep their original internal structure (access
codes under Smart Locks, credential management under ACS) — no extra
nesting level.

- Warning banners on both section overviews: low-level APIs; use
  Access Grants for granting; discuss other use cases with the Seam
  team (no deprecation commitment)
- Pointer hints on the granting-relevant sub-pages (access codes,
  managing credentials, ACS quick starts, ACS user management)
- .gitbook.yaml redirects for all 38 moved pages, plus retargeted
  pre-existing redirects that pointed into the moved trees
- Repo-wide link updates; cross-section relative links fixed by depth
