[Installables] configurable workloads dependencies

[podkidyshev]

Summary

Recent issue proved that we must keep everything configurable for users. This PR aims to address other potentially problematic parts of CloudAI, making sure users can choose versions of components used by workloads.

Test Plan

• Automated CI
• Manual runs of affected workloads
  • MBridge: 0.3.0 and 0.4.0
  • DynamoMocker
  • Other workloads were not tested as they don't alter default behavior anyhow

📝 Walkthrough

Walkthrough

Changes

The PR adds configurable repository versions, package requirements, and NumPy versions to multiple workloads. Repository properties refresh cached repositories and Python executables when versions change. Tests and reference scripts use the selected versions.

Configurable workload versions and requirements

Layer / File(s)	Summary
Configurable package requirements src/cloudai/workloads/aiconfig/aiconfigurator.py, src/cloudai/workloads/dynamo_mocker/dynamo_mocker.py	Command arguments now define package requirements. Python environments install the configured requirements.
AI Dynamo repository selection src/cloudai/workloads/ai_dynamo/ai_dynamo.py, tests/test_acceptance.py, tests/workloads/ai_dynamo/test_command_gen_strategy_slurm.py	AI Dynamo selects its repository from dynamo_version. Tests assign installation paths separately and verify the selected commit.
Megatron Bridge versioned runtime src/cloudai/workloads/megatron_bridge/megatron_bridge.py, src/cloudai/workloads/megatron_bridge/slurm_command_gen_strategy.py, tests/ref_data/megatron-bridge.sbatch	Megatron Bridge configures NeMo Run and NumPy versions. Generated commands and reference scripts use the selected versions.
NeMo Launcher version selection src/cloudai/workloads/nemo_launcher/nemo_launcher.py, src/cloudai/workloads/nemo_launcher/slurm_command_gen_strategy.py	NeMo Launcher selects its repository from launcher_version and removes that argument from generated launcher commands.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟠 High · up to edb57

Configurable runtime package versions are inserted into a shell wrapper without safe quoting, allowing crafted values to execute commands on the submit node. Merge should be blocked until both package specifications are shell-escaped.

In `@src/cloudai/workloads/megatron_bridge/slurm_command_gen_strategy.py`:
- Around line 393-395: Update the wrapper-generation logic around the runtime
dependency install command to shell-quote the complete wandb and numpy package
specifiers before interpolating them into the command, using the existing shlex
quoting approach. Ensure both wandb_version and numpy_version cannot inject
shell syntax while preserving the intended pip package constraints and error
handling.
