* Downcase signed_headers string before building the signed string

The HTTP Signatures draft does not mandate the “headers” field to be downcased,
but mandates the header field names to be downcased in the signed string, which
means that prior to this patch, Mastodon could fail to process signatures from
some compliant clients. It also means that it would not actually check the
Digest of non-compliant clients that wouldn't use a lowercased Digest field
name.

Thankfully, I don't know of any such client.

* Revert "Remove dead code (#8919)"

This reverts commit a00ce8c9.

* Restore time window checking, change it to 12 hours

By checking the Date header, we can prevent replaying old vulnerable
signatures. The focus is to prevent replaying old vulnerable requests
from software that has been fixed in the meantime, so a somewhat long
window should be fine and accounts for timezone misconfiguration.

* Escape users' URLs when formatting them

Fixes possible HTML injection

* Escape all string interpolations in Formatter class

Slightly improve performance by reducing class allocations
from repeated Formatter#encode calls

* Fix code style issues

of possible slight image quality decrease and processing resources.

Bug in #8559

If an unresolved report for the same target account already exists,
no new notification is generated

Mastodon converts all Emoji to images, whether they have a VS15 after
them or not, but leaves the VS15 in the string, which is displayed as
a black box in Safari.

* Fix the display of missing lists

See #6786 -- this fixes part of the issue pertaining to lists that don't exist. I copied the Column being returned from the missing status logic, which works fine. Prior to this, the missing lists logic would generate a column with no back button and with a broken layout. This doesn't fix the broken display of missing accounts -- the column construction pertaining to that logic happens in multiple external functions.

* import ColumnBackButton

missed the import with the first commit

Fix #8527

This restores the logic from before the public profile redesign. Fixes #8503

Add tests to avoid similar issues in the future
