[codex] Add Supabase Cloudflare network restriction helper

[riderx]

Summary (AI generated)

• Added scripts/update_supabase_network_restrictions.sh to apply current Cloudflare IPv4 and IPv6 CIDRs to Supabase database network restrictions.
• Added bun run supabase:allow-cloudflare as the package script entrypoint.
• Included dry-run, append, IPv4-only, IPv6-only, extra CIDR, profile, and env-file project ref support.

Motivation (AI generated)

Capgo needs an operational way to close direct Postgres access to Supabase while still allowing Cloudflare Hyperdrive to reach the database through Cloudflare egress ranges.

Business Impact (AI generated)

This improves database security posture by making it easier to restrict Supabase Postgres connectivity to Cloudflare-controlled paths, reducing direct exposure while preserving Hyperdrive-based operations.

Test Plan (AI generated)

• bash -n scripts/update_supabase_network_restrictions.sh
• bun -e 'JSON.parse(await Bun.file("package.json").text()); console.log("package.json ok")'
• bun run supabase:allow-cloudflare -- --project-ref xvwzpoazmxkqosrdewyv --dry-run --ipv4-only
• bun run supabase:allow-cloudflare -- --project-ref xvwzpoazmxkqosrdewyv --dry-run --ipv6-only
• bun run typecheck
