* GreenField: Notifications API
This refactors notifications so that we dont have a bunch of duplicated direct access to db contexts in controllers and then introduces new endpoints to fetch/toggle seen/remove notifications of the current user.
* add tests + docs
* fix test
* pr changes
* fix permission json
fixes#1958
Adds 2 new options:
* Do not allow stores to use the email settings of the server. Instead, they would need to fill in the email settings in their own store
* Do not allow user creation through the API unless you are an admin.
Both are opt-in and turned off by default.
This allows plugins to create custom dbcontexts, which would be namespaced in the scheme with a prefix. Migrations are supported too and the table would be prefixed too
* BTCPay Extensions Part 2
This PR cleans up the extension system a bit in that:
* It renames the test extension to a more uniform name
* Allows yo uto have system extensions, which are extensions but bundled by default with the release (and cannot be removed)
* Adds a tool to help you generate an extension package from a csproj
* Refactors the UI extension points to a view component
* Moves some more interfaces to the Abstractions csproj
* Rename to plugins
* Allow disabling notifications per user and disabling specific notifications per use
closes#1974
* Add disable notifs for all users
* fix term generator for notifications
* sow checkboxes instead of multiselect when js is enabled
* remove js dependency
* fix notif conditions
* Fix LN invoices
This commit adds more to the previous LN fix in the case of a partial payment to an invoice. While it generated a new LN invoice after 1 partial payment was made, there were some new issues uncovered:
* Any other subsequent partial payments was not listened to and did not generate an invoice ( fixed by listeneing to received payment event and makng sure that the status was already set `to partialPaid`)
* Any other subsequent partial payments caused a DbConcurrency error and did not generate an invoice ( Fixed in `MarkUnassigned`)
