Refactor frontend components to use Promise.all for parallel data fetching

[Tim020]

Summary

• Refactors 10 Vue components to use Promise.all for parallel API fetching
• Converts sequential await chains to parallel execution where operations are independent
• Improves page load times by running concurrent API calls instead of waiting for each to complete

Components Refactored

High Priority (Largest Impact)

Component	Before	After
ScriptEditor.vue	14 sequential awaits	Parallel groups with .then() chains
CueEditor.vue	13 sequential awaits	Parallel groups with .then() chains
ConfigMics.vue	6 sequential awaits	Single Promise.all

Medium Priority

Component	Changes
ConfigSystem.vue	4 independent fetches parallelized
ConfigCharacters.vue	2 independent fetches parallelized
CharacterGroups.vue	2 independent fetches parallelized
PropsList.vue	2 independent fetches parallelized
SceneryList.vue	2 independent fetches parallelized

Additional Optimizations

Component	Changes
App.vue	Parallelize RBAC roles with WebSocket state; parallelize user RBAC and settings
ShowLiveView.vue	Parallelize session data and act list fetches

Pattern Used

Following the existing pattern from ScriptViewPane.vue:

await Promise.all([
  // Independent operations run in parallel
  this.GET_SCENE_LIST(),
  this.GET_CHARACTER_LIST(),
  // Dependent chains use .then()
  this.GET_CURRENT_USER().then(() => {
    if (this.CURRENT_USER != null) {
      return Promise.all([
        this.GET_STAGE_DIRECTION_STYLE_OVERRIDES(),
        this.GET_CUE_COLOUR_OVERRIDES(),
      ]);
    }
    return Promise.resolve();
  }),
]);

Test plan

• ESLint passes with no errors
• All 83 Vitest tests pass
• Manual testing of affected pages to verify data loads correctly:
  • Script Editor
  • Cue Editor
  • Microphone Configuration
  • System Configuration
  • Character Configuration
  • Props/Scenery Configuration
  • Live Show View
