## Summary
Add SVG-based brand loading indicators (LogoCFillLoader,
LogoComfyWaveLoader) and use the wave loader as the app loading screen.
## Changes
- **What**: New `LogoCFillLoader` (bottom-to-top fill, plays once) and
`LogoComfyWaveLoader` (wave water-fill animation) components with
`size`, `color`, `bordered`, and `disableAnimation` props. Move all
loaders from `components/common/` to `components/loader/`. Use
`LogoComfyWaveLoader` in `App.vue` and `WorkspaceAuthGate.vue`. Render
loader above BlockUI overlay (z-1200) to prevent dim wash-out.
- **Dependencies**: None
## Review Focus
- SVG mask-based animation approach using `currentColor` for flexible
theming
- z-index layering: loader at z-1200 renders above PrimeVue BlockUI's
z-1100 modal overlay
- `disableAnimation` prop used in WorkspaceAuthGate to show static logo
outline during auth loading
