Mobiletic d119c366b7 test: add 5 multi-turn conversation examples
Scripted, deterministic conversations (fictional Swiss e-learning chats) via a
mock provider, each asserting exact per-turn round-trips + stable entity ids:
login support (attributes attach to PER_1), two learners (applyKnown reuse of a
re-mentioned name), old/new IBAN kept distinct, parent+minor+doctor (3 people),
and HR (manager+org reused, two employees). 46 tests total.
