feat: Implement Vision System API Client with comprehensive endpoints and utility functions

- Added VisionApiClient class to interact with the vision system API.
- Defined interfaces for system status, machine status, camera status, recordings, and storage stats.
- Implemented methods for health checks, system status retrieval, camera control, and storage management.
- Introduced utility functions for formatting bytes, durations, and uptime.

test: Create manual verification script for Vision API functionality

- Added a test script to verify utility functions and API endpoints.
- Included tests for health check, system status, cameras, machines, and storage stats.

feat: Create experiment repetitions system migration

- Added experiment_repetitions table to manage experiment repetitions with scheduling.
- Implemented triggers and functions for validation and timestamp management.
- Established row-level security policies for user access control.

feat: Introduce phase-specific draft management system migration

- Created experiment_phase_drafts and experiment_phase_data tables for managing phase-specific drafts and measurements.
- Added pecan_diameter_measurements table for individual diameter measurements.
- Implemented row-level security policies for user access control.

fix: Adjust draft constraints to allow multiple drafts while preventing multiple submitted drafts

- Modified constraints on experiment_phase_drafts to allow multiple drafts in 'draft' or 'withdrawn' status.
- Ensured only one 'submitted' draft per user per phase per repetition.
