refactor: scope destination and resource lookups by current team

Use find_destination_for_current_team helper across resource creation
flows and the destination controller. Pass full destination objects to
database creation helpers instead of UUIDs so team relationships are
resolved consistently before the resource is created or linked.

Add feature tests covering destination, backup storage, and resource
proof lookups across teams.
