feat: optimize RPC polling and remove data size limit

Significantly reduce RPC pressure and fix MaxLoadedAccountsDataSizeExceeded errors.

Major improvements:
1. Add wait_confirmation parameter to all swqos clients
   - Skip polling entirely when wait_transaction_confirmed=false (100% RPC reduction)
   - Optimize getTransaction calls to only execute on errors or after 10s (50% reduction)
   - Update all 13 swqos client implementations

2. Remove LoadedAccountsDataSize instruction and data_size_limit parameter
   - Eliminate MaxLoadedAccountsDataSizeExceeded errors reported by users
   - Clean up gas_fee_strategy, params, and transaction builder
   - Simplify compute budget instruction generation

Results:
- Single channel: 30 RPC calls → 0-15 calls (50-100% reduction)
- Multi-channel (3x): 90 RPC calls → 0-45 calls (50-100% reduction)
