[feature] SC-166737/improve app proxy security by restricting where token replacements can go

[HappyPaul55]

This pull request introduces improvements to how sensitive Zoom OAuth credentials are handled and simplifies the codebase by removing unused constants. The main focus is on securely injecting client_id and client_secret into request headers for OAuth calls, and cleaning up unused placeholder variables.

Zoom OAuth credential handling:

• Updated the Zoom OAuth endpoint configuration in manifest.json to inject client_id and client_secret into the Authorization headers for POST requests, improving security and flexibility.

Codebase cleanup:

• Removed unused placeholders for client_id and client_secret from src/constants.ts, reducing clutter and potential confusion.
