refactor(effects): Streamline uniforms initialization

Centralized uniforms_buffer_ initialization and updates to Effect base class:
- init_uniforms_buffer() now automatic in Effect::Effect()
- uniforms_buffer_.update() now automatic in dispatch_render()
- Removed redundant calls from all effect subclasses
- Updated effect.h comments to reflect automatic behavior
- Updated EFFECT_WORKFLOW.md templates

Benefits:
- 16 lines removed from effect implementations
- Consistent pattern enforced at compile time
- Reduced boilerplate for new effects

Tests: 34/34 passing
