Edit Flows

[needim]

The normal edit flow already handles all the cases outlined below, but it's important to understand this flow in detail. In gider.im, recurring entries are managed with a smart data approach, which requires us to address these specific scenarios. In the future, I plan to write tests to ensure that we can develop this feature confidently.

Read #8 for understanding recurring entries.

- If it's an exlclusion edit
	- just update the exclusion entry
- If it's a single entry edit
 	- just update the entry
- If it's a ghost record
	- create a new entry and exclusion

- If it's a recurring entry AND user checks "apply the subsequents"
	- If we are editing the main entry and there is no exclusions just update the entry
	- If we are not
		- update all future exclusions as "deletion"
		- stop the old recurring config (update recurringConfig)
		- create a new recurring config
		- create a new entry
		- create a new exclusion
