Export environment variables from .env.vagrant before running rails commands in Vagrant provisioning (#2343)

This provides a hotfix for outbound salmon requests to other Mastodon instances
as they currently will try to resovle user@WEB_DOMAIN instead of user@LOCAL_DOMAIN
(see #2012 and #20312).

Furthermore, this should ease transition from users switching from
LOCAL_DOMAIN = WEB_DOMAIN to another LOCAL_DOMAIN when WEB_DOMAIN does not change.

Put Column Slim Back Button classnames in order so it is positioned right and top. Add icon button style back to privacy dropdown and upload buttons so they are positioned correctly and do not wiggle. Remove abstracted style from CSS. Add missed class for the upload form thumbnail. Add the missed styles for upload form thumnail. Alphabetize styles for column-back-button. Fix fontSize typo for media-spoiler-video-play-icon.

The two methods `StreamEntriesHelper#stream_link_target` and
`StreamEntriesHelper#acct` are based on checking whether we are running
in an embedded view.

This adds some test helper code to make the testing easier. We extracted
some "magic strings" to constants to lower the coupling in the specs.

The code that generates CSS is based on a lot of boolean conditions.
The possible combinations of these grows exponentially as we add more
conditions.

Since most of the code is conditional on a single boolean, we tested the
following:

1. All `false`
2. All `true`
3. Each individual flag set to `true`

The methods tested are:

* `StreamEntriesHelper#style_classes`
* `StreamEntriesHelper#microformats_classes`
* `StreamEntriesHelper#microformats_h_class`

The previous translation for NSFW, "不適切" means "impertinent". This change
suggests "閲覧注意", which means the content requires precaution, instead.

However, "閲覧注意" was also a translation for CW. CW is now translated as
"警告", which simply means "warnings".

The force_ssl method from controllers does not add all of the options that the
sitewide configuration in a config block does. For example, HSTS enforcement is
not added by the controller method, but is added by this style.

* feat(aria): Add aria-labels to underlabelled tab nav items

The drawer tabs which control primary navigation are only labelled by a title which is not available to many screenreaders. Add an aria-label attribute to each link to improve readability with screenreaders. Organize link attributes so link target is first followed by classname.
Issue #1349

* feat(aria): Replace abstract aria role of section with region

Abstract aria roles such as section should not be used in content. Use non-abstract 'region' aria role instead. That role expects an aria-labelledby attribute with an id. Pass an ID to the column header. Remove the aria-label attribute on the ColumnHeader because the same value is output in plaintext as its child.
Issue #1349

* fix(aria): Remove aria-controls attribute until solution is found

Columns do not have wrappers, so these icons can't point to a column wrapper which it controls. Instead these icons function as triggers to show or hide individual columns.
#1349

* fix(typo): Remove type of aria-labelledby instead of aria-label

* add og:url to stream_item view

Updated to use a flow like:

- settings/two_factor_authentication goes to a #show view which has a button
  either enable or disable 2fa on the account
- the disable button turns off the otp requirement for the user
- the enable button cycles the user secret and redirects to a confirmation page
- the confirmation page is a #new view which shows the QR code for user
- that page posts to #create which verifies the code, and creates the recovery
  codes
- that create action shares a view with a recovery codes controller which can be
  used separately to reset codes if needed
