build: hold each message catalog to 250 KB gz, for the Russian one

Cyrillic is two bytes per letter in UTF-8, so the Russian catalog is
240 KB gz against under 210 for the Latin-script ones. The reason and the
numbers are in the budget file.

Numbers are KB gzip. routeBaselineKbGz is the measured first load of every page (the shared rootMainFiles plus the page's client-reference chunks, each file counted once by content hash), written with --write-baselines; a page fails when it is more than routeDriftAllowanceKbGz over its baseline, and a page without a baseline fails until one is written in the same change. firstLoadP95KbGz and firstLoadMaxKbGz cap the distribution across pages. uniqueClientKbGz caps the distinct client code: every module counted once by its module id, the lazy message catalogs excluded. maxCatalogKbGz holds each catalog, maxRechartsChunks the one shared chart chunk. The summed-chunk aggregate the gate used up to v1.44.0 (3875 KB there, capped at 3900) is still printed but no longer gated: it counted a module once per chunk group it landed in, so it rose whenever a page moved code into on-demand chunks and needed a raise in most releases while no reader downloaded more.

The five pages watched before keep their numbers within a kilobyte (/ 359, /measurements 339, /insights/mood 337, /insights 323, /settings/[section] 311), and the metric pages that no watched route covered before are gated now too (/insights/weight 339, /insights/pulse 339).
