feat(blocks): Add more Revid.ai media generation blocks (#9931)

<html><head></head><body><h3>Why these changes are needed 🧐</h3>
<p>Revid.ai offers several specialised, undocumented rendering flows
beyond the basic “text-to-video” endpoint our platform already
supported.
to:</p>
<ol>
<li>
<p><strong>Generate ads</strong> from copy plus product images
(30-second vertical spots).</p>
</li>
<li>
<p><strong>Turn a single creative prompt</strong> into a fully
AI-generated video (no multi-line script).</p>
</li>
<li>
<p><strong>Transform a screenshot into a narrated, avatar-driven
clip</strong>, ideal for product-led demos.</p>
</li>
</ol>
<p>Without first-class blocks for these flows, users were forced to drop
to raw HTTP nodes, losing schema validation, test mocks and credential
management.</p>
<h3>Changes 🏗️</h3>

Added new category to ``BlockCategory`` in ``block.py`` for ``MARKETING
= "Block that helps with marketing"``

Area | Change | Notes
-- | -- | --
ai_shortform_video_block.py | Refactored out a shared _RevidMixin
(webhook + polling helpers). | Keeps DRY across new blocks.
  | Added AudioTrack.DONT_STOP_ME_ABSTRACT_FUTURE_BASS and Voice.EVA
enum members. | Required by Revid sample payloads.
  | AIAdMakerVideoCreatorBlock | Implements ai-ad-generator flow;
supports optional input_media_urls, target_duration,
use_only_provided_media.
  | AIPromptToVideoCreatorBlock | Implements prompt-to-video flow with
prompt_target_duration.
  | AIScreenshotToVideoAdBlock | Implements screenshot-to-video-ad flow
(avatar narration, BG removal).
  | Added full pydantic schemas, test stubs & mock hooks for each new
block. | Ensures unit tests pass and blocks appear in UI.


<p>No existing functionality was removed; current <code
inline="">AIShortformVideoCreatorBlock</code> is untouched apart from
enum imports.</p></body></html>

### Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
  <!-- Put your test plan here: -->
- [x] use the ``AI ShortForm Video Creator`` block to generate a video
and it will work
- [x] same with `` ai ad maker video creator`` block test it and it
should work
  - [x] and test ``ai screenshot to video ad`` block it should work
