All instances should have a `data-modal-id` now. Throw a user-friendly error if this is not the case (custom templates, or missed cases).
Checked via `rg -P -e '^(?=.*delete-button)' | grep -v "data-modal-id"`
Removed two instances of delete modals and one case of simplified logic.
## Rationale
I am currently surveying the existing modals in Forgejo in the context of eventually replacing the modals implementation with our own modal implementation. This refactor fixes one of the many inconsistencies that the current usage of modals has. It should explicitly specify which modal should be used to avoids any problems if new modals are introduced on the page (for example via https://codeberg.org/forgejo/forgejo/pulls/8662).
