Update to React 19

[acho1833]

By all means, thank you so much for setting this template!. I really love the tech choices you have (especially zod-openapi and hono)

I'm trying to deploy with base code but keep getting

npm error   peer react@">=16.8.0" from @hookform/[email protected]
npm error   node_modules/@hookform/error-message
npm error     @hookform/error-message@"^2.0.1" from the root project
npm error   peer react@"^19.0.0" from [email protected]
npm error   node_modules/react-dom
npm error     peer react-dom@">=16.8.0" from @hookform/[email protected]
npm error     node_modules/@hookform/error-message
npm error       @hookform/error-message@"^2.0.1" from the root project
npm error   1 more (react-hook-form)

I am attempting to fix one by one but this error message seems to show up on another package. I would definitely appreciate if it can be updated. If not, that's fine and I'll eventually upgrade to latest version. Thanks!
