fix: apply snapshot configuration to remaining interactive tools

Fixes massive token overflow in browser_wait_for (284K tokens) and other
interactive tools by applying existing snapshot configuration system.

Updated tools with session-configurable snapshots:
- browser_wait_for (was generating 284,335 tokens\!)
- browser_handle_dialog
- browser_evaluate
- browser_file_upload
- browser_tab_select, browser_tab_new, browser_tab_close

All tools now:
✅ Respect browser_configure_snapshots settings
✅ Include updated descriptions mentioning session configurability
✅ Apply size limits, truncation, and differential modes automatically
✅ Can be controlled dynamically during sessions

This completes the comprehensive snapshot overflow solution covering
all interactive tools that generate accessibility snapshots.

Added SNAPSHOT_OVERFLOW_SOLUTION.md with complete usage guide and
quick fixes for token-constrained workflows.
