fix: uuid_generate_v7 integer overflow and seeder role constraint

Browse source 
Migration 009:
- Simplified uuid_generate_v7() to avoid integer overflow on bit shifts
- Uses double precision for timestamp then converts to hex

Seeder:
- Changed roles from 'admin','company' to 'companyAdmin'
- Matches users table CHECK constraint: superadmin, companyAdmin, recruiter, jobSeeker

-- Migration: Create UUID v7 generation function
-- Description: PostgreSQL function to generate UUID v7 (time-ordered UUIDs)
-- UUID v7 format: tttttttt-tttt-7xxx-yxxx-xxxxxxxxxxxx
-- Where: t = timestamp, 7 = version, y = variant, x = random
-- Uses gen_random_uuid() as base, then overrides first 6 bytes with timestamp
-- Enable pgcrypto extension for gen_random_bytes()
CREATE EXTENSION IF NOT EXISTS pgcrypto;
-- Create or replace the uuid_generate_v7 function
-- Simple UUID v7 function that works with PostgreSQL's type system
