The server's error, notification and share text and the module string
tables (orgs, codes, tournaments, stages, hosting) read the way an Egyptian
game talks: fewer words, no MSA, the loanwords players use (ماتش، ليفل،
كود، لينك، لايف). Server and app now say the same thing for the same error.
A bye is راحة everywhere; the queen is الوزير in the opening names too.

Fixes found on the way:
- Tournament refusals lost their numbers: the hosting catalog registers the
  plain err_* lines first, so "your rating is 1200, this starts at 1500"
  showed as "rating too low". refusalText() has its own refuse_* keys now.
- "wait N minutes" uses دقيقة، دقيقتين، دقايق by count.
- The certificate check page told people to scan a QR the PNG does not have.
- The double-elimination error said the stage was not a knockout.
