Summary

Fixes #421. In the main series Shedinja (#292) always has 1 HP. PokemonStatCalculator used the generic HP formula for every species, so the Pokédex stats section showed it with 11 to about 125 HP depending on level. Shedinja is reachable through Nincada's evolution branch.

HP is now pinned to 1 for species 292. Other stats and every other species are unchanged.

UI changes

Before	After
Shedinja stats at Lv50: HP about 67	Shedinja stats: HP 1

Validation

• New PokemonProfileLogicTests.testShedinjaAlwaysHasOneHP: HP is 1 at Lv1, Lv50 and Lv100, attack still follows the generic formula, and a non-Shedinja species with base HP 1 keeps the generic formula. On unfixed main it fails with 3 failures (11, 67 and 125 HP).
• Full swift test: 1385 tests, 0 failures (17 skipped, as on main).
• Added a defect-log entry.
