* fix(vertex-ai): pass litellm_params to validate_environment in video handlers and implement video edit for Veo
- Pass litellm_params to validate_environment in 11 video handler call sites
(remix, create_character, get_character, edit, extension, delete) so
DB-stored Vertex AI credentials are used instead of falling back to ADC
- Implement transform_video_edit_request/response for VertexAI: fetches
source video via fetchPredictOperation then submits a new
predictLongRunning request with the video bytes/gcsUri + edit prompt

* fix(vertex-ai): hoist fetchPredictOperation into handlers to avoid blocking event loop
- Add get_video_edit_prefetch_params() to BaseVideoConfig (returns None)
- VertexAI overrides it to return the fetchPredictOperation URL/body
- Both sync and async video_edit handlers call this and use their shared
httpx client for the fetch, passing the result as prefetched_source_data
- transform_video_edit_request is now a pure transform with no HTTP calls
- Fix extra_body.pop() mutation by working on a shallow copy

* fix(vertex-ai): include prefetch call inside _handle_error try/except block

* fix(videos): add prefetched_source_data param to all transform_video_edit_request overrides

* fix(video_edit): keep transform/pre_call outside try so validation errors propagate
Move transform_video_edit_request and logging_obj.pre_call outside the
try/except that wraps HTTP calls in (async_)video_edit_handler so that
ValueError validation errors (e.g. 'source video not complete yet') are
not silently wrapped as 500s by _handle_error. The prefetch HTTP call
keeps its own try/except so its errors are still mapped through the
provider's error handler. Matches the pattern used by
video_extension_handler and video_remix_handler.

* refactor(vertex_ai): delegate get_video_edit_prefetch_params to status retrieve

* Fix varia review
* fix(video_edit): route transform errors through _handle_error
Wrap transform_video_edit_request and pre_call in the same try/except
as the HTTP call in sync and async handlers so validation failures
(e.g. source video not complete) return typed LiteLLM exceptions.
