**What**
- Fixes an issue where we would parse a string like `"52 tests"` into `52` in the Metadata form
- If a row is deleted we now send off key with an empty string as its value to signify that it should be deleted. This is needed to introduce the API we had for updating metadata in V1. Adrien is implementing the BE support for this.
RESOLVES SUP-895
**What**
- Adds missing Metadata form for collections
- Fixes type of metadata in update payload
- Fixes an issue where deleting the last row of a metadata form would prevent adding new ones.
Resolves SUP-784
**What**
- Changes all forms to only submit on Cmd/Ctrl + Enter instead of just Enter.
- Cleans up the position of submit/cancel buttons in many FocusModals that still had them in the header.
- Fixes responsiveness of multiple forms
- Removes the SplitView component, and replaces its usages with StackedDrawer/Modal to align the UX across the project.
Resolves CC-103, CC-535
**What**
- Renames /admin-next -> /admin
- Renames @medusajs/admin-sdk -> @medusajs/admin-bundler
- Creates a new package called @medusajs/admin-sdk that will hold all tooling relevant to creating admin extensions. This is currently `defineRouteConfig` and `defineWidgetConfig`, but will eventually also export methods for adding custom fields, register translation, etc.
- cc: @shahednasser we should update the examples in the docs so these functions are imported from `@medusajs/admin-sdk`. People will also need to install the package in their project, as it's no longer a transient dependency.
- cc: @olivermrbl we might want to publish a changelog when this is merged, as it is a breaking change, and will require people to import the `defineXConfig` from the new package instead of `@medusajs/admin-shared`.
- Updates CODEOWNERS so /admin packages does not require a review from the UI team.
