refactor: use accountSequence as unified user identifier across all services

- planting-service: extract accountSequence from JWT, pass to referral-service
- referral-service: query by accountSequence instead of userId
- reward-service: add accountSequence field to schema and all layers
- wallet-service: prioritize accountSequence lookup over userId
- authorization-service: change userId from String to BigInt, add accountSequence

This change ensures consistent cross-service user identification using
accountSequence (8-digit unique business ID) instead of internal database IDs.
