refactor(period_utils): implement per-day relaxation with 4×4 matrix strategy

Browse source

Restructured relaxation mechanism to process each day independently instead
of globally, enabling different days to relax at different levels.

Key changes:
- Added hierarchical logging with INDENT_L0-L5 constants
- Replaced global relaxation loop with per-day relaxation (_relax_single_day)
- Implemented 4×4 matrix strategy (4 flex levels × 4 filter combinations)
- Enhanced _resolve_period_overlaps with replacement and extension logic
- Added helper functions: _group_periods_by_day, _group_prices_by_day,
  _check_min_periods_per_day

Relaxation strategy:
- Each flex level tries 4 filter combinations before increasing flex
- Early exit after EACH successful combination (minimal relaxation)
- Extensions preserve baseline metadata, replacements use relaxed metadata
- Only standalone periods count toward min_periods requirement

Impact: Users get more accurate period detection per day. Days with clear
cheap/expensive patterns use strict filters while difficult days relax as
needed. Reduces over-relaxation - finds 'good enough' solutions faster.
