Add script/TTS step handlers, dashboard, and pipeline UI (#35, #36, #43, #44)

StepHandler abstraction (app/Support/VideoWorkflow/StepHandlers/) plugs into WorkflowEngine without coupling it to how any given step type is actually executed: - ScriptGenerationHandler: builds a prompt from the project's title/ description (or an explicit outline/tone/keywords/target length in step input), generates via an active OpenAI AiProvider, stores the result as a 'script' asset. - TtsVoiceoverHandler: voices step.input.text, or falls back to the project's latest script asset, via an active ElevenLabs AiProvider; voice_id/model_id are configurable per step. No direct "speed" control — ElevenLabs' base TTS endpoint doesn't expose one. RunWorkflowStepJob resolves a step's handler by type and runs it on the queue, matching the existing PublishPostJob pattern (including a stale-dispatch guard: no-op if the step isn't 'in_progress' anymore). UI, under its own /video-projects routes and nav entry — separate from /projects per the earlier decision: - VideoProjects/Index (#43): list projects with status and step progress, create new ones. - VideoProjects/Show (#44): start a project from a WorkflowTemplate or a hardcoded default 8-step pipeline; per-step Run/Approve/Reject/ Retry/Skip actions; auto-queues the next step after any transition when a handler exists for its type (steps with no handler yet just sit in_progress rather than auto-failing); lists project assets.
