v0.14.4

Fixed

• The Infrastructure page's "saved, but not applied yet" notice no longer disappears for the rest of the session — it was suppressed by a latch that is set when a save succeeds and cleared only by a restart's page reload, so from the first successful save none of the four cards could report a setting that was still waiting on a restart, which is the one state the notice exists for.
• A dashboard save no longer overwrites the saved engine with a stale running one — the engine radio seeded from the running engine, which the gateway resolves once at boot, so after an engine change that had not been restarted yet a save of any unrelated field wrote the old engine back over the operator's choice; the radio now seeds from the saved configuration, which the previous release only did when an environment variable pinned the setting.
• The send-pacing documentation now matches the code on bulk sends — .env.example and the API specification said bulk sends were counted exactly against the warm-up cap, but a bulk item the engine refuses is checked against the cap without ever being counted into it, because bulk writes its row only after the send succeeds.
