Make the resume bilingual and part of the shared site chrome

Adds a Russian version (data/resume.ru.json, default language) with an RU/EN
switch stored under the key shared with the front page and the portfolio.
The top bar becomes the site-wide one (brand, Resume, Portfolio, Gitea,
Contact, language, theme) with a second row of anchors for this page's
sections, and the fonts move to Unbounded and Onest so the three pages share
one type system. Portfolio links now point at /portfolio/.
