android-emulator: import orphaned namespace into state (lock-race recovery)

Pipeline 85 created the namespace but a Terraform pg-backend
workspace-creation lock race (new stack schema initializing while other
stacks applied concurrently) left it out of the recorded state — every
later apply then died with 'namespaces android-emulator already exists'.
Adopt it with an import block per the house recovery pattern; stanza
gets removed once it has applied.
