🤖 refactor: Remove Default Model Params for All Endpoints (#3682)

* refactor: use parseCompactConvo in buildOptions, and generate no default values for the API to avoid weird model behavior with defaults

* refactor: OTHER - always show cursor when markdown component is empty (preferable to not)

* refactor(OpenAISettings): use config object for setting defaults app-wide

* refactor: Use removeNullishValues in buildOptions for ALL  endpoints

* fix: add missing conversationId to title methods for transactions; refactor(GoogleClient): model options, set no default, add todo note for recording token usage

* fix: at minimum set a model default, as is required by API (edge case)
