Analytics Dashboard — Trend charts, market insights, portfolio metrics

[GareBear99]

Overview

Add analytics dashboard with historical trend tracking, market insights, and portfolio performance metrics.

Scope

• Price trend charts — median price over time by city/province
• DOM distribution — days-on-market histogram
• Score distribution — deal score bell curve across inventory
• Lead conversion funnel — new → contacted → qualified → closed
• Market velocity — new listings vs sold rate per market
• Portfolio summary — total potential value, avg deal score, coverage gaps

Technical Notes

• Canvas-based charts (no external chart library — keep zero-dependency)
• Data already available in pipeline: price history, DOM, scores, lead status
• Consider a dedicated analytics.html page or dashboard tab

Acceptance Criteria

• At least 3 chart types implemented
• Data sourced entirely from existing pipeline artifacts
• No external dependencies added
