Numerous component files have been renamed for better organization and readability. This includes changing 'app' to 'account-layout' in various instances and 'organization' to 'team' to ensure consistency across code. Additionally, dependencies within codes have been updated in line with the renaming. The pull request also includes a minor update to the pnpm-lock file, reflecting the latest version of Next.js.
This commit updates various components in the billing flow due to a new schema that supports multiple line items per plan. The added flexibility rendered 'line-items-mapper.ts' redundant, which has been removed. Additionally, webhooks have been created for handling account membership insertions and deletions, as well as handling subscription deletions when an account is deleted. This message also introduces a new service to handle sending out invitation emails. Lastly, the validation of the billing provider has been improved for increased security and stability.
