Compatibility with Open WebUI >= 0.9.0 (async DB APIs) — venice_image_generation

[NickFranceschina]

Summary

Open WebUI v0.9.0 converted the Files and Functions DB helpers to async def. The venice_image_generation pipe calls two of these synchronously, which on >=0.9.0 raises at import/request time (e.g. RuntimeWarning: coroutine ... was never awaited, 'coroutine' object is not subscriptable).

This is the same root cause (and follows the same approach) as #258, which fixed the gemini pipe/filter. This PR applies the equivalent fix to the Venice pipe while keeping behavior identical on older versions that still expose the same method names.

Version bumped: 0.10.1 → 0.11.0.

plugins/pipes/venice_manifold.py

• Removed the sync Functions.get_function_valves_by_id("venice_image_generation") call from Pipe.__init__. It's async upstream and would raise at import time. __init__ now uses self.Valves() defaults. Open WebUI's pipe pipeline assigns the DB-backed valves onto the instance before every pipes/pipe call, so configured valves still take effect at runtime. The existing pipes() method already detects LOG_LEVEL changes and reruns the logging setup once real valves land.
• Dropped the now-unused from open_webui.models.functions import Functions import.
• _upload_image promoted to async; await Files.insert_new_file(...). Call site in pipe() updated to await self._upload_image(...).
• Storage.upload_file remains sync upstream — wrapped in asyncio.to_thread(...) (both the has_tags and legacy branches) so it doesn't block the event loop now that the method is async.

Validation

• ast.parse clean.
• Diff is scoped to exactly this one file.
• Tested live against a local Open WebUI >= 0.9.0: image generation + Files-API upload work, and the import-time coroutine errors are gone.
