<!-- Clearly explain the need for these changes: -->
This PR adds general-purpose video editing blocks for the AutoGPT
Platform, enabling automated video production workflows like documentary
creation, marketing videos, tutorial assembly, and content repurposing.
### Changes 🏗️
<!-- Concisely describe all of the changes made in this pull request:
-->
**New blocks added in `backend/blocks/video/`:**
- `VideoDownloadBlock` - Download videos from URLs (YouTube, Vimeo, news
sites, direct links) using yt-dlp
- `VideoClipBlock` - Extract time segments from videos with start/end
time validation
- `VideoConcatBlock` - Merge multiple video clips with optional
transitions (none, crossfade, fade_black)
- `VideoTextOverlayBlock` - Add text overlays/captions with positioning
and timing options
- `VideoNarrationBlock` - Generate AI narration via ElevenLabs and mix
with video audio (replace, mix, or ducking modes)
**Dependencies required:**
- `yt-dlp` - For video downloading
- `moviepy` - For video editing operations
**Implementation details:**
- All blocks follow the SDK pattern with proper error handling and
exception chaining
- Proper resource cleanup in `finally` blocks to prevent memory leaks
- Input validation (e.g., end_time > start_time)
- Test mocks included for CI

<!-- CURSOR_SUMMARY -->
---
> [!NOTE]
> **Medium Risk**
> Adds new multimedia blocks that invoke ffmpeg/MoviePy and introduces
new external dependencies (plus container packages), which can impact
runtime stability and resource usage; download/overlay blocks are
present but disabled due to sandbox/policy concerns.
>
> **Overview**
> Adds a new `backend.blocks.video` module with general-purpose video
workflow blocks (download, clip, concat w/ transitions, loop, add-audio,
text overlay, and ElevenLabs-powered narration), including shared
utilities for codec selection, filename cleanup, and an ffmpeg-based
chapter-strip workaround for MoviePy.
>
> Extends credentials/config to support ElevenLabs
(`ELEVENLABS_API_KEY`, provider enum, system credentials, and cost
config) and adds new dependencies (`elevenlabs`, `yt-dlp`) plus Docker
runtime packages (`ffmpeg`, `imagemagick`).
>
> Improves file/reference handling end-to-end by embedding MIME types in
`workspace://...#mime` outputs and updating frontend rendering to detect
video vs image from MIME fragments (and broaden supported audio/video
extensions), with optional enhanced output rendering behind a feature
flag in the legacy builder UI.
