- models.py: add composite (user_id, date) indexes to flock_history,
feed_purchases, and other_purchases for faster date-filtered queries
(egg_collections already had one via its unique constraint)
- main.py: add v2.2 migration to create the three composite indexes on
existing installs at startup
- stats.py: fix N+1 query in monthly_stats — flock history is now fetched
once and looked up per month using bisect_right instead of one DB query
per month row; also remove unnecessary Decimal(str(...)) round-trips
since SQLAlchemy already returns Numeric columns as Decimal
- eggs.py: add limit parameter (default 500, max 1000) to list_eggs to
cap unbounded fetches on large datasets
- dashboard.js: pass start= (30 days ago) when fetching eggs so the
dashboard only loads the data it actually needs for the chart and
recent collections list
