✨ feat(agent-runtime): server-side human approval flow (#13829)

* ✨ feat(agent-runtime): implement server-side human approval flow

Port the client-mode human approval executors (request_human_approve,
call_tool resumption, handleHumanIntervention) to the server agent
runtime so that execServerAgentRuntime can correctly pause on
waiting_for_human and resume on approve / reject / reject_continue.

- request_human_approve now creates one `role='tool'` message per pending
  tool call with `pluginIntervention: { status: 'pending' }` and ships
  the `{ toolCallId → toolMessageId }` mapping on the `tools_calling`
  stream chunk.
- call_tool gains a `skipCreateToolMessage` branch that updates the
  pre-existing tool message in-place (prevents duplicate rows / parent_id
  FK violations that show up as LOBE-7154 errors).
- AgentRuntimeService.handleHumanIntervention implements all three
  paths: approve → `phase: 'human_approved_tool'`; reject → interrupted
  with `reason: 'human_rejected'`; reject_continue → `phase: 'user_input'`.
- ProcessHumanIntervention schema carries `toolMessageId` and a new
  `reject_continue` action; schema remains permissive (handler no-ops on
  missing toolMessageId) to keep legacy callers working.

Fixes LOBE-7151

* 🐛 fix(agent-runtime): address LOBE-7151 review (P1 reject_continue, P2 duplicate tool msg)

P1 — reject_continue with remaining pending tools must NOT resume the LLM.
Previously `handleHumanIntervention` kept `status='waiting_for_human'` but
returned `nextContext: { phase: 'user_input' }`, which `executeStep` would
hand to `runtime.step` immediately, breaking batch semantics. Now when
other tools are still pending, the rejection is persisted but no context
is returned; the `user_input` continuation only fires when this is the
last pending tool.

P2 — request_human_approve was pushing an empty placeholder
`{ role: 'tool', tool_call_id, content: '' }` into `newState.messages`
to "reflect" the newly-created pending DB row. On resume, the `call_tool`
skip-create path appends the real tool result, leaving two entries for
the same `tool_call_id` in runtime state. The downstream short-circuit
(`phase=human_approved_tool` → `call_tool`) doesn't consult
state.messages, so the placeholder was unused cost. Removed.

Also fixes a TS 2339 in the skipCreateToolMessage test where
`nextContext.payload` is typed `{}` and needed an explicit cast.

Tests: 99 pass (82 RuntimeExecutors + 17 handleHumanIntervention), type-check clean.
Verified end-to-end via the human-approval eval — it now exercises a
multi-turn retry path (LLM calls the gated tool twice) and both
approvals resolve cleanly through to `completionReason=done`.

* pin @react-pdf/renderer

* 🐛 fix(deps): pin @react-pdf/image to 3.0.4 to avoid privatized @react-pdf/svg

@react-pdf/image@3.1.0 (auto-resolved via layout@4.6.0 ← renderer@4.4.1)
declares `@react-pdf/svg@^1.1.0` as a dependency, but the svg package was
unpublished/made private on npm (returns 404). CI installs blow up with
ERR_PNPM_FETCH_404.

Upstream issue: https://github.com/diegomura/react-pdf/issues/3377

Pin image to 3.0.4 (the last release before the broken svg dep was
introduced) via pnpm.overrides until react-pdf publishes a fix.
