Updated Bootstrap Script Changes to support /connection endpoint changes

[pacific-ring]

• All new/changed/fixed functionality is covered by tests (or N/A)
• I have added documentation for all new/changed functionality (or N/A)

📋 Changes

Fix: adopt Auth0's new /connections/{id}/clients endpoint

• Stop sending the deprecated enabled_clients field in connection create/update bodies (Auth0 now rejects it with a 400).
• Add getConnectionEnabledClients() — reads the paginated /connections/{id}/clients sub-resource; returns null (unknown/missing scope) vs [] (none enabled).
• Add ensureClientEnabledOnConnection() — enables the app via additive PATCH and verifies by re-reading (PATCH returns 204).
• Make checkDatabaseConnectionChanges() async; merge passkey options instead of overwriting.

Feature: configurable application name

• Add --client-name= flag / AUTH0_CLIENT_NAME env / interactive prompt (resolveClientName, validateClientName).
• Replace hardcoded CLIENT_NAME with DEFAULT_CLIENT_NAME + setClientName/getClientName module state.
• Add promptWithUser() helper (free-text prompt with default + non-TTY fallback).

Add back the NOTICE.md

[SurajThotakura]

@pacific-ring why are we removing the NOTICE.md file. Can you check if this is by mistake?

[pacific-ring]

Good catch — that removal was unintentional. I've restored NOTICE.md in e80b903.
