Merge pull request 'fix(vault): rename applications.policies → ops_policies (cms CI was silently missing its R2 policy)' (#4) from claude/fix-cms-ops-policies-key into main

The `applications` object field was declared `policies` in variables.tf, but
the cms tfvars entry, the runbook (doc/runbooks/new-web-app/03-vault-platform.md),
the guidebook (vibe/guidebooks/tools/secrets-and-vso.md) and the module input
(modules/app_policy variable `ops_policies`) all use the name `ops_policies`.

Because Terraform silently drops unknown attributes when converting a value to
an object() type, cms's `ops_policies = ["factory__cf_r2_arcodange_tf"]` was
discarded and `each.value.policies` fell back to [] — so gitea_cicd_cms never
received the `factory__cf_r2_arcodange_tf` token policy (read on
kvv1/cloudflare/r2/arcodange-tf + kvv1/zoho/self_client, defined in
factory iac/cloudflare.tf). cms CI was missing its Cloudflare R2 Terraform-state
permissions.

Fix at the root: rename the schema field `policies` -> `ops_policies` (and its
single reference main.tf:82 `each.value.policies` -> `each.value.ops_policies`),
aligning the whole chain. This is lower-churn than renaming the tfvars key (the
chosen alternative would also have required fixing the runbook + guidebook, which
both already document `ops_policies`) and prevents the next app created from the
runbook from re-introducing the same silently-dropped key.

Behavioural change: gitea_cicd_cms gains `factory__cf_r2_arcodange_tf` in its
token_policies. No other app sets this field (all default []), so no other role
changes. Reviewer: confirm the R2 policy is the intended grant for cms CI.
