feat(loan-origination): guarantor share-account verification, committee resolution gating, legal doc uploads, CIC score-detection fixes, and interest/share rate chart

- Guarantor must be a real existing client with a verified active share account, with clickable share-account chips
- Loan Committee Approval now requires Resolution No./Date plus a full application report before approving
- Loan Committee gets its own pre-filtered pipeline view via a menu link and stage query param
- Legal Approval stage gets a multi-file document upload checklist with add-more support
- CIC PDF parser: item-level score detection before line-based fallback, fixing font-size-driven line-merging misdetection
- New Interest & Share Rate Chart tab: per-product interest/tenure bands and per-amount-slab Share Capital linkage requirements
