feat: tenant config routing — platform → service triple (BJ-11)

Problem#

Dispatch-path services (PhaseRouterService, PhaseHooksService, CompoundService) import GitHubService directly, making it impossible to route multi-platform events to the correct concrete service. This blocks Bitbucket/Jira dispatch in Wave 3.

Task / Link#

Closes #551 (BJ-11: Tenant config routing — platform → service triple)

Changes#

• New src/tenant/platform-services.ts — PLATFORM_SERVICES injection token + PlatformServicesMap type
• New src/tenant/tenant-config.service.spec.ts — unit tests for getPlatformServices() (happy path, unknown platform, missing platform)
• Extend TenantConfigService.getPlatformServices(platform) — returns { service, adapter, authProvider } triple; throws BadRequestException on empty platform, NotFoundException on unknown platform
• Promote AdapterRegistry to PlatformModule (providers + exports), removing it from WebhookModule to break potential circular dependency
• Update TenantModule — registers PLATFORM_SERVICES factory { github: GitHubService }, imports PlatformModule
• Refactor PhaseRouterService — drops GitHubService injection; routes validateCompoundScope through tenantConfig.getPlatformServices('github').service
• Refactor PhaseHooksService and CompoundService — replace direct GitHubService injection with TenantConfigService; all GitHub calls now routed through getPlatformServices()
• Update all three spec files to inject a TenantConfigService stub returning the service triple

Notes#

• postFeedbackComment in PhaseRouterService continues to use PlatformServiceResolver (the minimal PlatformProvider interface), which handles the platform-agnostic postComment call already established in BJ-11 (PR #587). getPlatformServices() is complementary: it exposes the full concrete service for GitHub-specific methods not covered by PlatformProvider.
• Typing service as GitHubService in the return type is intentional and temporary — PlatformProvider expansion to cover more methods is deferred to Wave 3 sibling tickets.

Testing#

• npm run lint — zero warnings
• npm run test — 994/994 passing (154 new/updated assertions in 4 spec files)
• Grep audit: grep -r "from '../github/github.service'" src/phase-router src/hooks → zero matches
