refactor(auth): rename forcePrompt to forceSelection and fix AuthManager type

CHANGES:
- Rename forcePrompt option to forceSelection in EnsureOrgOptions interface
- Update all call sites in export.command.ts and commands.js
- Fix AuthManager type in export.command.ts by importing from @tm/core
- Replace dirty (this.taskMasterCore.auth as any).authManager hack with AuthManager.getInstance()
- Use type import for AuthManager in org-selection.ts
