fix: Add omit empty optional fields in update bot payloads (#111)

* Added optional "suggest reply" settings for bots to configure reply
mode and custom prompt.
* Create and Update bot payloads now omit empty optional fields,
enabling smaller/partial JSON payloads for optional settings.
* Required identifier fields remain unchanged and are still always
included in requests.
