Change all account actions except "none" to resolve all unresolved reports

Refactor `SuspendAccountService` to be more readable

- Remove --background option
- Add --concurrency(=5) option
- Add progress bars

To (somewhat) limit mass remote follow. Fix #11360

* Add "--exclude-suspended" to tootctl domains crawl

This new option ignores any instances suspended server-wide as
well as their associated subdomains. This queries all domain
blocks up front, then runs a regexp on each domain. This improves
performance over what may be the obvious implementation, which is
to ask `DomainBlocks.blocked?(domain)` for each domain -- this
hits the DB many times, slowing things down considerably.

* cleaning up code style

* Compiling regex

* Removing ternary operator

* Add `tootctl preview_cards remove`

* fix code style

* Remove `Scheduler::PreviewCardsCleanupScheduler` file

* fix code style again
Add exclude case where image_file_name is blank

* Added a function to output confirmation if the specified number of days is less than 2 weeks

Fix #7940

* Bump version to 2.8.3

* Bump version to 2.8.4

* Record account suspend/silence time and keep track of domain blocks

* Also unblock users who were suspended/silenced before dates were recorded

* Add tests

* Keep track of suspending date for users suspended through the CLI

* Show accurate number of accounts that would be affected by unsuspending an instance

* Change migration to set silenced_at and suspended_at

* Revert "Also unblock users who were suspended/silenced before dates were recorded"

This reverts commit a015c65d2d.

* Switch from using suspended and silenced to suspended_at and silenced_at

* Add post-deployment migration script to remove `suspended` and `silenced` columns

* Use Account#silence! and Account#suspend! instead of updating the underlying property

* Add silenced_at and suspended_at migration to post-migration

* Change account fabricator to translate suspended and silenced attributes

* Minor fixes

* Make unblocking domains always retroactive

* Remove custom emojis on domains purge

* Change message "Removing" to "Removed"

Add `--approve` option to `tootctl accounts modify`

* config: Add GITHUB_REPOSITORY for repository name

* config: Add SOURCE_BASE_URL for repository url

* Show source_url and repository name on getting started

* Add `tootctl accounts reset`

* Rename reset to reset-relationships

* Improve command description

Fix #10441

* List the actual accounts that would have been culled during a dry run.

Otherwise, the dry run mode is basically useless.

* Prevent unreachable domains from inheriting the previous status code.

* Update CHANGELOG.md for #10460.
