Price Paperboy at $5/month with daily and weekly rollups

[cgallic]

Summary

• price the existing hosted self-serve plan at $5/month after the seven-day trial
• add first-class daily and weekly rollup choices; weekly subscribers choose Monday-Sunday
• persist cadence and weekday through additive SQLite migration with existing rows defaulting to daily
• enforce due schedules at 8:00 AM in each subscriber's IANA timezone
• expose the saved schedule and next delivery through confirmation and management flows
• record cadence as consented, PII-free funnel analytics
• make newpaperboy.com canonical while preserving paperboy.kaibuilds.com as a compatibility host
• replace the stale $49 strategy and document required Stripe production settings without adding secrets

Validation

• 67 pytest tests passed, including migration and weekly scheduler edge cases
• Playwright product smoke passed: weekly selection, subscribe, confirmation, Stripe handoff, active trial, management status, unsubscribe, failures, mobile, privacy, and terms
• product static checks passed
• Ruff and diff checks passed
• GitHub CI runs on Python 3.10 and 3.12
