full terminology overhaul + zakat fund types + fund allocation

POSITIONING FIX — PNPL is NOT just 'QR codes at events':
- Charities collecting at events (QR per table)
- High-net-worth donor outreach (personal links via WhatsApp/email)
- Org-to-org pledges (multi-charity projects)
- Personal fundraisers (LaunchGood/Enthuse redirect)

TERMINOLOGY (throughout app):
- Events → Campaigns (sidebar, pages, create dialogs, onboarding)
- QR Codes page → Pledge Links (sharing-first, QR is one option)
- Scans → Clicks (not just QR scans)
- 'New Event' → 'New Campaign'
- 'Create QR Code' → 'Create Pledge Link'
- Source label: 'Table Name' → 'Source / Channel'

SHARING (pledge links page):
- 4-button share row: Copy · WhatsApp · Email · More (native share)
- Each link shows its full URL
- Create dialog suggests: 'WhatsApp Family Group, Table 5, Instagram Bio'
- QR code is still shown but as one option, not the hero

LANDING PAGE (complete rewrite):
- Hero: 'Collect pledges. Convert them into donations.'
- 4 use case cards: Events, HNW Donors, Org-to-Org, Personal Fundraisers
- 'Share anywhere' section: WhatsApp, QR, Email, Instagram, Twitter, 1-on-1
- Platform support: Bank Transfer, LaunchGood, Enthuse, JustGiving, GoFundMe, Any URL
- Islamic fund types section: Zakat, Sadaqah, Sadaqah Jariyah, Lillah, Fitrana

ZAKAT & FUND TYPES:
- Organization.zakatEnabled toggle in Settings
- Pledge.fundType: general, zakat, sadaqah, lillah, fitrana
- Identity step: fund type picker (5 options) when org has zakatEnabled
- Zakat note: Quran 9:60 categories reference
- Settings: toggle card with fund type descriptions

FUND ALLOCATION:
- Event.fundAllocation: 'Mosque Building Fund', 'Orphan Sponsorship' etc.
- Charities can also add external URL for reference/allocation (not just fundraisers)
- Shows on campaign cards and pledge flow
