fix: Schema compatibility - emoji → icon column rename

Production Outline DB uses 'icon' column instead of 'emoji' for documents
and revisions. Fixed all affected queries:

- documents.ts: SELECT queries
- advanced-search.ts: Search queries
- analytics.ts: Analytics + GROUP BY
- export-import.ts: Export/import metadata
- templates.ts: Template queries + INSERT
- collections.ts: Collection document listing
- revisions.ts: Revision comparison

reactions.emoji kept unchanged (correct schema)

Tested: 448 documents successfully queried from hub.descomplicar.pt
