v0.16.2

ADR-0040 accepted by the owner

Owner decision O0 on issue #335 accepted ADR-0040 (AW Business Platform capability ownership and boundaries) as written: D1, D2 and D4 stand unamended, so Booking, the hr_payroll family and generic delivery stay upstream-first in ahliweb/awcms (#915 to #918).

• ADR-0040 and its Indonesian mirror are set to Accepted with a decision record; the ADR index row follows.
• docs/aw-business-platform-dor.md drops the answered O0 row and marks Wave A item A1 done. O1 to O12 remain open, and A6 to A8 stay blocked on them.
• Documentation only: no code, module, migration or OpenAPI path is added (ADR-0040 D7).

Sync apps/cms to upstream AWCMS v10.6.0

apps/cms now embeds ahliweb/awcms main at 61507bb7 (AWCMS v10.6.0), two commits past the previous sync (a0dabcd9).

• idn-admin-regions dataset rollback (ahliweb/awcms#914, #922): now() is the transaction start, so the active dataset could be stamped equal to or earlier than the one it superseded, and the strict activated_at < filter then found nothing to roll back to. Rollback now takes the latest superseded dataset by (activated_at, id) with no comparison. Covered by a new integration test.
• Version bump to 10.6.0 with upstream's CHANGELOG.md and PROJECT_STATE updates. No new migrations, no dependency changes.
• No standing local divergence was resolved or added. The only conflict was in apps/cms/docs/PROJECT_STATE.md and its Indonesian mirror (upstream's version and release-note rows against this embed's module and migration counts); both lineages were kept and the mirror restamped.
