Cleaned up stale references to the removed posts and stats apps

[9larsons]

ref https://linear.app/ghost/issue/PLA-246/

The posts/stats packages dissolved into apps/admin domain folders, but a number of docs and code comments still pointed at the deleted apps/posts/apps/stats paths — including AGENTS.md directing new admin features to apps/posts.

Comment/doc-only; no behavior change.

• AGENTS.md — admin-apps inventory, koenig-lexical consumers, the Tailwind @source lists (now matching apps/admin/src/index.css), and the "where to build new admin features" guidance
• docker/dev-gateway/README.md — served-apps note
• vitest.config.mjs — watch-filter example + a sentence about the long-gone admin-x-activitypub directory
• configs/eslint-react/index.mjs — @example header named a deleted config file; made generic
• ghost/core .../schema/views.js — cross-reference to the member subscription-resolution consumer, now at apps/admin/src/members/member-query-params.ts (and no longer a getCurrentSubscription helper)
• automations email utils (8 files) — the duplicated-file NOTEs pointed at the deleted posts copies; they now point at the real counterpart in the other app so the keep-in-sync constraint survives
• apps/admin/src/routes.tsx — dropped a comment narrating the dissolved PostsAppContext
• shared-views.ts ×2 — dropped TODOs whose "once the apps are merged" premise is satisfied (the layout hook already delegates to the members parser)
• shade-page-templates skill — trigger list/glob no longer names posts/stats

Deliberately left: apps/shade's posts-stats transitional subpath and the docs describing it — that subpath still exists and is removed separately.

Verification

• eslint clean on all touched JS/TS files (also enforced by lint-staged on commit)
• grep -rn 'apps/posts\|apps/stats' across the repo now only matches the intentionally-kept shade posts-stats files

It looks like this PR contains a migration 👀
Here's the checklist for reviewing migrations:

General requirements

• ⚠️ Tested performance on staging database servers, as performance on local machines is not comparable to a production environment
• Satisfies idempotency requirement (both up() and down())
• Does not reference models
• Filename is in the correct format (and correctly ordered)
• Targets the next minor version
• All code paths have appropriate log messages
• Uses the correct utils
• Contains a minimal changeset
• Does not mix DDL/DML operations
• Tested in MySQL and SQLite

Schema changes

• Both schema change and related migration have been implemented
• For index changes: has been performance tested for large tables
• For new tables/columns: fields use the appropriate predefined field lengths
• For new tables/columns: field names follow the appropriate conventions
• Does not drop a non-alpha table outside of a major version

Data changes

• Mass updates/inserts are batched appropriately
• Does not loop over large tables/datasets
• Defends against missing or invalid data
• For settings updates: follows the appropriate guidelines

Walkthrough

Updated repository guidance and documentation to reflect the consolidated Admin React shell and its admin-x-settings and activitypub embedded apps. Adjusted Shade trigger paths, Tailwind source references, development gateway notes, Koenig import guidance, and Admin UI development instructions. Updated duplicated email helper comments to reference current locations, removed obsolete TODO and refactor comments, and refreshed supporting references in ESLint, schema, and Vitest documentation.

Possibly related PRs

• TryGhost/Ghost#28960: Both changes update the shade-page-templates skill and its autoTrigger scope.
• TryGhost/Ghost#29213: Both changes touch useSharedViews in apps/admin/src/layout/app-sidebar/shared-views.ts.
