This addresses an issue where the second row of translation flags are not

`height` of "auto" so that the entire div fits the flags’ surface area,
making them clickable again.

This adds an enhancement to the Canned Response Select2 showing more options

Removed the span, it was unnecessary and gave the Internal Note button
a color to differentiate between Reply and Internal Note.

Moved buttons above with other action buttons and also into sticky
header. Removed titles of buttons and added tooltips. adjusted tooltip
z-index so it won’t be hidden behind dropdowns. added scroll to bottom
function to reply and internal note buttons.

Adds an additional location for the ticket response above the ticket
thread for a reverse order view of the ticket thread. Additionally the
reply/internal note button would be selected and the page would auto
scroll to the bottom.

This is necessary to differentiate true system notes vs. notes made by a
deleted agent or collaborator.

Load and cache all the attachments on a thread prior to rendering the items.
That removes the need to run a query per thread item to check for- and fetch
attachments.

Furthermore, ensure that the HTML is properly rendered on the client and
staff ticket view pages.

Adjusted all tables to use % instead of px.

Styled dashboard page.

FAQ tweaks: fixed buttons, adjusted layout for all pages concerning FAQ, resolved Consistency issues.

And two flags, one which signals that stored HTML is correctly balanced and

Additionally, this patch fixes showing external inline images (via the [Show
Images] button) when clicked.
