Calculate metrics from first relevant event to now (capped at 30 days)
instead of a fixed 30-day window. This fixes inaccurate metrics for new
users who have only a few days of data.
Changes:
- Add _get_first_event_ts() and _calculate_window() helpers to stats.py
- Add window_days field to EggStats dataclass
- Update routes/eggs.py and routes/feed.py to use dynamic window
- Update templates to display "N-day avg" instead of "30-day avg"
- Use ceiling division for window_days to ensure first event is included

Add comprehensive E2E acceptance tests for stats progression:
- Test #1: Baseline eggs/feed/costs with 13 ducks
- Test #2: Mixed group proration with juveniles
- Test #3: Split flock per-location stats
- Test #4: Backdated eggs use historical roster
- Test #5: Event edit with revision tracking
Tests use cumulative fixtures building on each other.
Note: Some cost_per_egg_layers values differ from spec due to
integer bird-day truncation in implementation vs fractional
in spec calculations.
