Julian Pawlowski 1e1c8d5299 feat(periods): handle flat days and absolute low-price scenarios 
Three complementary fixes for pathological price days:

1. Adaptive min_periods for flat days (CV ≤ 10%):
   On days with nearly uniform prices (e.g. solar surplus), enforcing
   multiple distinct cheap periods is geometrically impossible.
   _compute_day_effective_min() detects CV ≤ LOW_CV_FLAT_DAY_THRESHOLD
   and reduces the effective target to 1 for that day (best price only;
   peak price always runs full relaxation).

2. min_distance scaling on absolute low-price days:
   When the daily average drops below 0.10 EUR (10 ct), percentage-based
   min_distance becomes unreliable. The threshold is scaled linearly to
   zero so the filter neither accepts the entire day nor blocks everything.

3. CV quality gate bypass for absolute low-price periods:
   Periods with a mean below 0.10 EUR may show high relative CV even
   though the absolute price differences are fractions of a cent.
   Both _check_period_quality() and _check_merge_quality_gate() now
   bypass the CV gate below this threshold.

Additionally: span-aware flex warnings now emit INFO/WARNING when
base_flex >= 25%/30% and at least one "normal" (non-V-shape) day
exists (FLEX_WARNING_VSHAPE_RATIO = 0.5). Previously the constants
were defined but never used.

Updated 3 test assertions in test_best_price_e2e.py: the flat-day
fixture (CV ~5.4%) correctly produces 1 period, not 2.

Impact: Best Price periods now appear reliably on V-shape solar days
and flat-price days. No more "0 periods" on days where the single
cheapest window is a valid and useful result.
