## Description
This PR fixes an issue where editing a contact name from the “Contacts”
tab would not allow spaces in the First or Last Name fields — the space
would disappear immediately after typing.
This issue did not occur in the sidebar editor or when adding a new
contact.
**Cause:** The form had a deep watcher on `contactData`, which triggered
`prepareStateBasedOnProps()` on every nested change. This caused the
form state to reset.
**Solution:** Replaced the deep watcher with a shallow watcher that only
watches `contactData.id`.
This fires once on mount and whenever a new contact is selected,
avoiding unnecessary re-hydration while the user is typing.
