1ba1ab7fe2 [json] Document heap fallback buffer sizing expectations
Payloads exceeding 1024 bytes are not known to exist in real
configurations. One doubling iteration covers all known entity types.
Cap at 4096 as a safety limit.

90ed0db0d9 [json] Replace measureJson() with doubling strategy in heap fallback
Avoids instantiating DummyWriter templates (~736 bytes flash) by
doubling the heap buffer until the payload fits. The temporary
over-allocation (at most 2x) is acceptable since payloads exceeding
the 512-byte stack buffer are rare.

6a7925b3ce [json] Fix SerializationBuffer truncation when payload exceeds stack buffer
ArduinoJson's serializeJson() with a bounded buffer returns the actual
bytes written (truncated count), NOT the would-be size like snprintf().
When the payload exceeded the 512-byte stack buffer, the return value
was used as the exact size for heap reallocation, but this was only the
truncated count. The heap buffer was allocated too small, the second
serialization was also truncated, and no NUL terminator was written.

This caused corrupted JSON in SSE streams for entities with payloads
exceeding 512 bytes (e.g., climate DETAIL_ALL with many features).

Fix: use measureJson() in the heap fallback path to get the exact
untruncated size before allocating. Also add the missing set_size_()
call after the second serialization to ensure proper NUL termination.

aa870483f1 Reduce SerializationBuffer stack size from 768 to 512 bytes
768 bytes on the httpd task stack contributes to stack overflow when
combined with other stack-allocated buffers (query string parsing, etc.).
512 bytes still covers all typical JSON payloads (sensors ~200B, lights
~170B, climate ~500-700B). Only extreme edge cases with 40+ options
trigger heap fallback.
