feat: implement oracle system with tests

[big14way]

This PR implements a robust oracle system for the MusicStrk platform, enabling decentralized performance evaluation and data validation for music auditions. The system includes comprehensive testing with 23 test cases covering all major functionalities.

Key Features

1. Oracle Management
   Authorization and deauthorization of oracles
   Oracle reputation tracking
   Staking mechanism for oracles
   Oracle metadata management (reputation score, submission history, specialization)
2. Data Submission Capabilities
   Performance evaluations with detailed scoring
   Vote submissions with validation
   Session status updates
   Credential verification
   Batch operations support
3. Validation & Security
   Score validation (0-100 range)
   Confidence level checks (1-100)
   Verification level validation (1-5)
   Authorization checks for all oracle operations
   Data integrity validation
4. Consensus Mechanisms
   Multi-oracle consensus system
   Weighted scoring based on oracle reputation
   Conflict resolution handling
   Consensus threshold management

Hello boss @big14way I see you restructured the season and audition contract and it looks amazing having good separation of concerns.
now the thing with this that there are other implementations that are already coming in which followed the current implementation and also inherit it too.
immediate change of structure will disrupt there implementation. lets focus a bit on the current issue.
