Modernize pacx wr setEnvImage to use CustomThemeDefinition (env/app scope) with local theme support

[Copilot]

pacx wr setEnvImage was still using legacy theme mechanics and did not support per-app modern theme overrides. This updates the command to manage logo changes through CustomThemeDefinition, including app-scoped usage and local theme.xml workflows.

• Command surface update

  • Added optional --appId / --appName to target app-level setting values.
  • Added optional --localThemeFile to update and reuse a local theme.xml.
  • Added argument validation for mutually exclusive app selectors and GUID format checks for --appId.

• Modern theme setting flow (CustomThemeDefinition)

  • Resolves scope automatically:
    • environment-level (default)
    • app-level (when --appId or --appName is provided)
  • Reads CustomThemeDefinition setting value from organizationsetting or appsetting.
  • When setting already points to a theme webresource:
    • loads XML
    • updates logo node to the selected image webresource
    • persists (and optionally updates local file)
  • When setting is missing/empty:
    • with --localThemeFile: updates local theme XML, pushes it as webresource, updates setting value
    • without --localThemeFile: creates theme.xml under publisherprefix_/themes/, optionally saves locally in .wr.pacx context, pushes it, updates setting value

• Dataverse integration consistency

  • Reuses established webresource upsert and solution-association patterns.
  • Publishes the updated/created theme webresource after write.
  • Normalizes publisher-prefix folder behavior to avoid malformed prefix__ paths.

• Focused test coverage

  • Added parser/validation tests for new options and constraints.
  • Added executor tests for:
    • existing CustomThemeDefinition webresource update path
    • missing-setting + missing-default-solution failure path

# environment-level logo update
pacx webresources setEnvImage -n new_logo.png

# app-level logo update
pacx webresources setEnvImage -n new_logo.png --appName SalesHub
# or
pacx webresources setEnvImage -n new_logo.png --appId 00000000-0000-0000-0000-000000000000

# local theme file workflow
pacx webresources setEnvImage -n new_logo.png --localThemeFile .\new_\themes\theme.xml
