Code Review
This pull request updates the Gemini model identifiers in the backend configuration and frontend input form, moving from preview versions to a new naming convention. The reviewer identified that the specified model names (e.g., gemini-2.5-flash) are incorrect and will result in API 404 errors, suggesting they be corrected to the stable gemini-1.5 series instead.

The model name gemini-2.5-flash is incorrect. Google's current stable models are in the 1.5 series (e.g., gemini-1.5-flash). Using a non-existent model name will result in API 404 errors. Additionally, please ensure that reflection_model and answer_model (lines 19 and 26) are also updated to use the correct 1.5 versions for consistency.

The default model state should be updated to a valid model identifier. gemini-2.5-flash does not exist; the stable version is gemini-1.5-flash.

The model identifier gemini-2.5-flash is incorrect and will likely cause a 404 error. It should be gemini-1.5-flash. Note that the UI label '2.5 Flash' on line 143 should also be updated to '1.5 Flash' for accuracy, although it is not part of the modified lines in this diff.

The model identifier gemini-2.5-pro is incorrect. The correct stable identifier is gemini-1.5-pro. Similar to the Flash model, the display label on line 151 should also be updated to '1.5 Pro'.

Problem
Several Gemini model names used in this project are deprecated and return
404 errors for new users, making the project impossible to run out of the box.
gemini-2.0-flash: no longer available to new users. Google has officiallyannounced deprecation with shutdown scheduled for June 1, 2026.
