feat(twitter): Implement random sleep and improve login process

[teslashibe]

Description

This PR introduces improvements to our Twitter scraping authentication process to make it more robust and less detectable as automated behavior.

Changes

1. In config.go:

   • Introduced RandomSleep() function to add variability in request timing
   • Set sleep duration range from 500ms to 2s
   • Initialized a package-level random number generator for thread-safety

2. In auth.go:

   • Updated NewScraper() to use RandomSleep() before and after login attempts
   • Improved error handling and logging in the login process

Rationale

These changes aim to make our scraping behavior more human-like and reduce the risk of being detected as a bot or having our accounts suspended. By introducing random delays between actions, we mimic natural user behavior more closely.

Testing

• Tested login process with multiple accounts
• Verified that random sleep durations are being applied correctly
• Ensured that error handling and logging are working as expected
