[5.x] Enhance Telescope Clear Method

[a1383n]

This PR refines the clear method in the Laravel Telescope DatabaseEntriesRepository for a more efficient and reliable table-clearing process.

Key Improvements:

• Safe Truncate: The method now attempts to truncate the telescope_entries and telescope_monitoring tables using Schema::withoutForeignKeyConstraints, effectively managing foreign key constraints.
• Fallback to Chunked Deletion: If truncation fails due to a PDOException, the method automatically falls back to chunked deletion, ensuring that the clearing process completes smoothly.
• Performance Boost: Truncation is significantly faster than chunked deletion, optimizing the clearing process while preserving fallback options for reliability.

References:

• This PR resolves issues introduced in [4.x] Updated db command for clearing tables #991, where truncation without handling foreign keys caused failures.
• It maintains the chunked deletion logic added in fix: clear all entries using chunks #1415 and Prune command fails to delete records then using with mysql on planetscale #1410 to support databases with row deletion limits.

This solution is stable, backward-compatible, and ready for review.
