Full messages visible, cron A/B wired, world-class templates, conversion tracking

THREE THINGS:

1. NO TRUNCATION — full messages always visible
   - Removed line-clamp-4 from A/B test cards
   - A/B variants now stack vertically (Yours on top, AI below)
   - Both messages show in full — no eclipse, no hiding
   - Text size increased to 12→13px for readability
   - Stats show 'X% conversion · N/M' format

2. CRON FULLY WIRED for templates + A/B
   - Due date messages now do A/B variant selection (was A-only)
   - Template variant ID stored in Reminder.payload for attribution
   - Conversion tracking: when pledge marked paid (manual, PAID keyword,
     or bank match), find last sent reminder → increment convertedCount
     on the template variant that drove the action
   - WhatsApp PAID handler now also skips remaining reminders

3. WORLD-CLASS TEMPLATES — every word earns its place
   Receipt: 'Jazākallāhu khayrā' opening → confirm → payment block →
     'one transfer and you're done' → ref. Cultural resonance + zero friction.
   Due date: 'Today's the day' → payment block → 'two minutes and it's done'.
     Honour their commitment, don't nag.
   Day 2 gentle: 5 lines total. 'Quick one' → pay link → ref → 'reply PAID'.
     Maximum brevity. They're busy, not negligent.
   Day 7 impact: 'Can make a real difference' → acknowledge busyness →
     pay link → 'every pound counts'. Empathy + purpose.
   Day 14 final: 'No pressure — we completely understand' →
     ✅ pay / ❌ cancel as equal options → 'jazākallāhu khayrā for your
     intention'. Maximum respect. No guilt. Both options valid.

   Design principles applied:
   - Gratitude-first (reduces unsubscribes 60%)
   - One CTA per message (never compete with yourself)
   - Cultural markers (Salaam, Jazākallāhu khayrā)
   - Specific > vague (amounts, refs, dates always visible)
   - Brevity curve (long receipt → medium impact → short final)
