feat(bladectl)!: add more bladectl commands (#91)

Browse Source 
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

when having multiple compute-blades in your bladeconfig:

```yaml
blades:
    - name: 1
      blade:
        server: blade-pi1:8081
        cert:
            certificate-authority-data: <redacted>
            client-certificate-data: <redacted>
            client-key-data: <redacted>
    - name: 2
      blade:
        server: blade-pi2:8081
        cert:
            certificate-authority-data: <redacted>
            client-certificate-data: <redacted>
            client-key-data: <redacted>
    - name: 3
      blade:
        server: blade-pi3:8081
        cert:
            certificate-authority-data: <redacted>
            client-certificate-data: <redacted>
            client-key-data: <redacted>
    - name: 4
      blade:
        server: blade-pi4:8081
        cert:

            client-certificate-data: <redacted>
            client-key-data: <redacted>
    - name: 4
      blade:
        server: blade-pi4:8081

            certificate-authority-data: <redacted>
            client-certificate-data: <redacted>
            client-key-data: <redacted>
current-blade: 1
```

Fixes #4, #9 (partially), should help with #5

* test: improve unit-testing

* fix: pin github.com/warthog618/gpiod
