feat: add workflow missing-tools install request button

When a workflow run fails because required tools are not installed, Galaxy
now detects which tools are missing and surfaces a one-click
'Request Installation' button so users can notify admins without leaving
the workflow run page.

Backend changes:
- workflows.py: pass missing_tool_ids as extra_error_info on the
  MessageException so the list is serialised into the JSON error response
- notifications.py: add optional tool_ids and workflow_name fields to
  ToolRequestNotificationContent so admin notifications include the
  workflow context
- tool_request_form.py: mirror the same two fields on ToolRequestFormData
  and wire them through to the notification content
- test_tool_request_form.py: add integration test that submits a request
  with tool_ids + workflow_name and verifies both appear in the admin
  notification

Frontend changes (client/src/components/Workflow/Run/):
- services.js: add WorkflowMissingToolsError class (extends Error, carries
  missingToolIds[]); update getRunData() catch to detect missing_tool_ids
  in the error response and throw the typed error before rethrowSimple()
  would strip structured data
- WorkflowMissingToolsRequest.vue: new component — shows a button with
  count badge, a GModal confirmation dialog, and uses localStorage keyed
  on the sorted tool-ID set to disable the button after a successful
  request (avoids hammering); hidden for anonymous users and when the
  feature flag enable_tool_request_form is false; falls back gracefully
  when workflowName is not yet available
- WorkflowMissingToolsRequest.test.ts: 25-test suite covering visibility
  rules (feature flag, anonymous, empty IDs), cancel path, payload shape,
  singular/plural copy, localStorage deduplication, storage-key sorting,
  in-flight disabled state, error recovery/retry, and modal re-open
- WorkflowRun.vue: import and render WorkflowMissingToolsRequest inside
  the danger BAlert when a WorkflowMissingToolsError is caught; call
  getWorkflowInfo() as a best-effort fallback to populate workflowName on
  both the standard and instance (props.instance) code paths
- schema.ts: add tool_ids and workflow_name to ToolRequestFormData type
