feat(swqos): add minimum tip constants and conditional transaction building

- Define minimum tip constants for each SWQOS provider (JITO, NextBlock, Node1, etc.)
- Add dynamic filtering in execute_parallel to skip transaction building when tip is below provider's minimum
- Add missing SWQOS_ENDPOINTS_ASTRALANE constant
- Ensure SWQOS clients are always initialized but transactions are conditionally built based on current tip amount
