This commit removes the final vestiges of `bootstrap-btn.css` from
portico, allowing us to move `bootstrap-btn.css` from `common.ts` bundle
to just `app.ts` bundle.
This commit is a part of the efforts to rename btn-related classes
and variables to align with Zulip's no-abbreviations policy and
streamline the search results.
We used "btn-primary" class only in integrations dev panel page
and this commit re-adds the CSS applied by this class in
integrations_dev_panel.css. We also remove the btn-primary class
since this is a bootstrap-specific class and we no longer
need it.
This commit adds "bootstrap-focus-style" class to the select
elements such that we can add CSS rule for focusing a select
element at single place only using this class.
Adds HTML title elements to templates that extend either `base.html`,
`portico.html` or `portico_signup.html`, and that are not website
portico landing pages that will use the `PAGE_TITLE` variable to set
the HTML title element (see following commit in series).
Also, updates some templates for missing translation tags.
As a general rule, we want the title element (and page content)
translated. Exceptions that are updated in this commit are templates
used in the development environment, analytics templates that are used
by staff and templates related to Zephyr.
This reverses the policy that was set, but incompletely enforced, by
commit 951514dd7d. The self-closing tag
syntax is clearer, more consistent, simpler to parse, compatible with
XML, preferred by Prettier, and (most importantly now) required by
FormatJS.
