[codex] harden authenticated routes and issue editor reliability (#3741)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - The control plane depends on authenticated routes enforcing company
boundaries and role permissions correctly
> - This branch also touches the issue detail and markdown editing flows
operators use while handling advisory and triage work
> - Partial issue cache seeds and fragile rich-editor parsing could
leave important issue content missing or blank at the moment an operator
needed it
> - Blocked issues becoming actionable again should wake their assignee
automatically instead of silently staying idle
> - This pull request rebases the advisory follow-up branch onto current
`master`, hardens authenticated route authorization, and carries the
issue-detail/editor reliability fixes forward with regression tests
> - The benefit is tighter authz on sensitive routes plus more reliable
issue/advisory editing and wakeup behavior on top of the latest base

## What Changed

- Hardened authenticated route authorization across agent, activity,
approval, access, project, plugin, health, execution-workspace,
portability, and related server paths, with new cross-tenant and
runtime-authz regression coverage.
- Switched issue detail queries from `initialData` to placeholder-based
hydration so list/quicklook seeds still refetch full issue bodies.
- Normalized advisory-style HTML images before mounting the markdown
editor and strengthened fallback behavior when the rich editor silently
fails or rejects the content.
- Woke assigned agents when blocked issues move back to `todo`, with
route coverage for reopen and unblock transitions.
- Rebasing note: this branch now sits cleanly on top of the latest
`master` tip used for the PR base.

## Verification

- `pnpm exec vitest run ui/src/lib/issueDetailQuery.test.tsx
ui/src/components/MarkdownEditor.test.tsx
server/src/__tests__/issue-comment-reopen-routes.test.ts
server/src/__tests__/activity-routes.test.ts
server/src/__tests__/agent-cross-tenant-authz-routes.test.ts`
- Confirmed `pnpm-lock.yaml` is not part of the PR diff.
- Rebased the branch onto current `public-gh/master` before publishing.

## Risks

- Broad authz tightening may expose existing flows that were relying on
permissive board or agent access and now need explicit grants.
- Markdown editor fallback changes could affect focus or rendering in
edge-case content that mixes HTML-like advisory markup with normal
markdown.
- This verification was intentionally scoped to touched regressions and
did not run the full repository suite.

## Model Used

- OpenAI Codex, GPT-5-based coding agent in the Codex CLI environment
with tool use for terminal, git, and GitHub operations. The exact
runtime model identifier is not exposed inside this session.
