[patch] Add validation for customization archive name in interactive installation

[PalVala]

Problem

• Installation fails when customization archive names contain spaces or invalid characters, causing this Kubernetes API error:

  Invalid value: "Custom Archive": spec.settings.customizationList[0].customizationArchiveName
  in body should match '^[0-9a-zA-Z][0-9a-zA-Z-_.]+$'

Solution

• Added client-side validation to catch invalid names early during interactive installation.

Changes:

• Added CustomizationArchiveNameValidator class in python/src/mas/cli/validators.py
• Applied validator to customization archive name prompt in python/src/mas/cli/install/settings/manageSettings.py
• Validation Rules
• Must start with alphanumeric character (a-z, A-Z, 0-9)
• Can contain: alphanumeric, hyphens (-), underscores (_), periods (.)
• No spaces allowed

User Experience

• Invalid input is rejected immediately with a clear error message and automatic re-prompt:

  Customization archive name: CustomMas
  Invalid format. Must start with alphanumeric character and contain only
  alphanumeric characters, hyphens (-), underscores (), and periods (.). No spaces allowed.
  Customization archive name: CustomMas

Files Changed:

• python/src/mas/cli/validators.py
• python/src/mas/cli/install/settings/manageSettings.py
