* fix(fancontroller): support more than 2 steps in fan curve
The GetFanSpeedPercent function only used the first 2 steps from the
config, ignoring all subsequent steps. This caused the fan to cap at
step[1]'s percent value regardless of actual temperature.
For example, with a typical 5-step curve:
- 40°C → 30%
- 50°C → 50%
- 60°C → 70%
- 70°C → 90%
- 75°C → 100%
Any temperature ≥50°C would return 50% instead of the correct value.
At 77°C the fan should be at 100%, but was stuck at 50%.
The fix properly iterates through all configured steps to find the
correct temperature bracket and interpolates within it.

This PR introduces a comprehensive set of new subcommands to bladectl, expanding its capabilities for querying and managing compute blade state. It also includes an internal refactor to simplify interface management across the gRPC API.
* `get`
* `fan`: Returns current fan speed.
* `identify`: Indicates whether the identify mode is active.
* `stealth`: Shows if stealth mode is currently enabled.
* `status`: Prints a full blade status report.
* `temperature`: Retrieves current SoC temperature.
* `critical`: Shows whether critical mode is active.
* `power`: Reports the current power source (e.g., PoE+ or USB).
* `set`
* `stealth`: Enables stealth mode.
* `remove`
* `stealth`: Disables stealth mode.
* `describe`
* `fan`: Outputs the current fan curve configuration.
* `monitor`: plot some charts about the state of the compute-blade-agent
* **gRPC API refactor**: The gRPC service definitions previously located in `internal/api` have been folded into `internal/agent`. This eliminates redundant interface declarations and ensures that all ComputeBladeAgent implementations are directly compatible with the gRPC API.
This reduces duplication and improves long-term maintainability and clarity of the interface contract.
```bash
bladectl set fan --percent 90 --blade 1 --blade 2
bladectl unset identify --blade 1 --blade 2 --blade 3 --blade 4
bladectl set stealth --blade 1 --blade 2 --blade 3 --blade 4
bladectl get status --blade 1 --blade 2 --blade 3 --blade 4
