Implemented Status Table

[GaminRick7]

Created a status table to get supervisor info (will be updated to fetch data from heartbeat):

• Stores supervisor info in redis hash with status, GPU type, timestamps
• Returns JSON with supervisor details

Endpoints implemented:

/supervisors/status          # See all supervisors
/supervisors/status/{id}     # Check specific supervisor  
/supervisors                 # All supervisors (with ?active=true filter)

Testing: Added 3 dummy supervisors to the status table for testing purposes:

• worker_amd_001 - AMD GPU, Active
• worker_nvidia_002 - NVIDIA GPU, Active
• worker_tt_003 - TT, Inactive

Test using the following endpoints:

/supervisors/status
/supervisors/status/worker_amd_001
/supervisors/status/worker_nvidia_002
/supervisors/status/worker_cpu_003
/supervisors
/supervisors?active=true

overall functionality looks good, but need unit tests (via go test)
