refactor: introduce writable handles to signify updates to handle ref…

…erences

A special list of writable handles is compiled in a list while issuing handles (request/collection creation, etc). Instead of manually computing the tab and toggling the dirty state, the writable handle is updated (changing the type to invalid on request deletion) and the tab with the request open can infer it via the update reflected in the request handle under the tab save context (reactive update trigger).
