fix(tests): fix all 39 failing specs and re-enable pre-commit hook

- Fix circular dependency in guildwar-attack/defence: import FortificationCardContentComponent directly instead of via @components/shared barrel
- Add index === -1 guard in guildwar-attack, guildwar-defence, guildwar-teams _setChampionsByPower to avoid crash when members input is empty
- Fix MembersStatisticsComponent to guard against undefined member in ngOnInit
- Fix JumpComponent: initialize jump with sautants/author defaults to avoid template crash
- Add provideRouter([]), provideHttpClient(), provideAnimations(), provideNativeDateAdapter() to 26 spec files missing them
- Register Chart.js scales in chart component specs
- Rewrite FrenchPaginator spec to instantiate service directly
- Fix AppComponent spec assertions to match actual component
- Re-enable npm test in .husky/pre-commit
