chore: Add internal feature flags for Chatwoot Cloud (#10902)

This PR introduces internal feature flags for testing purposes. These
flags will not be displayed on regular instances to prevent customer
confusion.

Additionally, a new feature flag, `contact_chatwoot_support_team`, has
been added for Chatwoot Cloud. This flag disables contact support for
third-party onboarded accounts, as support will be handled by the
original affiliate team.
