Verified Origin v4.0.0 Elite Launch Build

Highlights:
- Adds controlled badge sizing (Compact, Medium and Full) and left/centre/right shortcode alignment.
- Retains four floating badge positions and adds size control to floating badges.
- Adds tier-aware upgrade prompts throughout Client Pro, with direct links to the relevant pricing section.
- Makes Professional features such as deeper Trust History and advanced Claim Review visibly gated.
- Makes Business multi-site, higher-volume and priority workflows clearly discoverable.
- Adds founding launch pricing references: Starter £7.99/month, Professional £19.99/month, Business £39.99/month.
- Adds pricing cards to the Lite upgrade screen.
- Keeps gpt-4.1-mini as the proven OpenAI default and adds a fallback-model setting so newer GPT-5.6 models can be tested safely once exact API identifiers are confirmed.
- Preserves cautious wording: Verified Origin supports human review and does not legally verify a business, prove identity, guarantee originality or certify that a website is safe.

SureCart note:
The plugin now exposes the agreed launch pricing in its plan metadata and upgrade UI. SureCart product/price records must still be changed in SureCart and their exact price IDs entered in Licensing Core before launch.

Post-install tests:
1. Update Licensing Core, Cloud Pro, Master Pro and Client Pro in that order.
2. Test Lite separately.
3. Validate each plan licence and confirm its scan/site allowance.
4. Test floating badge positions and all three badge sizes.
5. Test shortcode size/alignment overrides.
6. Confirm locked Professional and Business prompts link to the correct pricing anchors.
7. Run a scan and verify OpenAI output, fallback behaviour, reports and badge suppression.
