Julian Pawlowski ced9d8656b fix(chartdata): assign vertical transition lines to more expensive segment
Problem: In segmented price charts with connect_segments=true, vertical lines
at price level transitions were always drawn by the ending segment. This meant
a price INCREASE showed a cheap-colored line going UP, and a price DECREASE
showed an expensive-colored line going DOWN - counterintuitive for users.

Solution: Implement directional bridge-point logic using price level hierarchy:
- Add _is_transition_to_more_expensive() helper using PRICE_LEVEL_MAPPING and
  PRICE_RATING_MAPPING to determine transition direction
- Price INCREASE (cheap → expensive): The MORE EXPENSIVE segment draws the
  vertical line UP via new start-bridge logic (end-bridge at segment start)
- Price DECREASE (expensive → cheap): The MORE EXPENSIVE segment draws the
  vertical line DOWN via existing end-bridge logic (bridge at segment end)

Technical changes:
- Track prev_value and prev_price for segment start detection
- Add end-bridge points at segment starts for upward transitions
- Replace unconditional bridge points with directional hold/bridge logic
- Hold points extend segment horizontally when next segment handles transition

Impact: Vertical transition lines now consistently use the color of the more
expensive price level, making price movements more visually intuitive.
