feat: add captain editor events (#13524)

## Description

Adds missing analytics instrumentation for the editor AI funnel so we
can measure end-to-end usage and outcome quality.

### What was added

- Captain: Editor AI menu opened
- Captain: Generation failed
- Captain: AI-assisted message sent

### Behavior covered

- Tracks AI button click + menu open from both entry points:
    - top panel sparkle button
    - inline editor copilot button
- Tracks generation failures (initial + follow-up stages).
- Tracks whether accepted AI content was sent as-is or edited before
send.

### Notes

- Applies to editor Captain accept/send flow
(rewrite/summarize/reply_suggestion + follow-ups).
- Does not change Copilot sidebar flow instrumentation.

## Type of change

- [x] Bug fix (non-breaking change which fixes an issue)
- [x] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality not to work as expected)
- [ ] This change requires a documentation update

## How Has This Been Tested?

1. Open a conversation with Captain tasks enabled.
2. Click AI button in top panel and inline editor.
3. Confirm analytics events fire for:
    - AI menu opened
4. Run an AI action and force a failure scenario (or empty response
path) and confirm generation-failed event.
5. Accept AI output, then:
    - send without changes -> editedBeforeSend: false
    - edit then send -> editedBeforeSend: true
