Refactor gdrive_downloader.py - Google auth session for private doc…

[milovate]

…uments

• Used a double-check locking to ensure that multiple threads won't create redundant auth sessions simultaneously.

Q/A checklist

• If you add new dependencies, did you update the lock file?

poetry lock --no-update

• Run tests

ulimit -n unlimited && ./scripts/run-tests.sh

• Do a self code review of the changes - Read the diff at least twice.
• Carefully think about the stuff that might break because of this change - this sounds obvious but it's easy to forget to do "Go to references" on each function you're changing and see if it's used in a way you didn't expect.
• The relevant pages still run when you press submit
• The API for those pages still work (API tab)
• The public API interface doesn't change if you didn't want it to (check API tab > docs page)
• Do your UI changes (if applicable) look acceptable on mobile?
• Ensure you have not regressed the import time unless you have a good reason to do so.
  You can visualize this using tuna:

python3 -X importtime -c 'import server' 2> out.log && tuna out.log

To measure import time for a specific library:

$ time python -c 'import pandas'

   sys time    0.72 secs  613.00 micros    0.72 secs

To reduce import times, import libraries that take a long time inside the functions that use them instead of at the top of the file:

def my_function():
    import pandas as pd
    ...

Legal Boilerplate

Look, I get it. The entity doing business as “Gooey.AI” and/or “Dara.network” was incorporated in the State of Delaware in 2020 as Dara Network Inc. and is gonna need some rights from me in order to utilize my contributions in this PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Dara Network Inc can use, modify, copy, and redistribute my contributions, under its choice of terms.

Walkthrough

The changes implement thread-safe lazy initialization for the global Google authentication session in daras_ai_v2/asr.py by introducing a threading lock and updating the get_google_auth_session function to support custom scopes and double-checked locking. In daras_ai_v2/gdrive_downloader.py, the Google Docs export logic now uses the authenticated session from get_google_auth_session for requests requiring Google Drive access. In daras_ai_v2/vector_search.py, the error message for inaccessible Google Drive documents is enhanced to include the service account email and clearer instructions, using HTML formatting for improved user guidance. No public API signatures were changed except for the updated parameter in get_google_auth_session.
