feat: migrate auth from supabase to better auth (#596)

* feat: add README for @cio/db package and remove existingAccounts.json

* load session, load profile and organization, add create profile hook

* chore: cache session request

The trick was passing all the cookies to the backend. Previously I was only passing the better-auth.session_token and not better-auth.session_data. Read about the difference here https://www.better-auth.com/docs/concepts/cookies#custom-cookies

* feat: login, logout, onboarding, verify email, reset password.

* feat: complete change email and email verification

* feat: standardise how we make rpc calls and create org endpoints

* fix ui errors

* fix: handle potential undefined customerId and standardize avatar URL property

* refactor: standardize custom domain handling and update telegram chat ID references

* chore: add tailwind prefix to @cio/ui

this fixed the media query issues because  @cio/ui classes were overriding this dashboard tailwind build

* chore: clean up org sidebar

* chore: persist mode state

* feat: implement order breadcrumbs

* chore: upgrade to better auth 1.4

* chore: address common auth flow bugs and setup app for others to setup locally.
