New Crowdin updates (#266)

The /session/ page crashed when a tracked player's tank stats included
a tank with no matching tank definition or no average stats (WN8
baseline). The delta memo dereferenced `tank.id` on a possibly missing
definition and forced `average?.mu!` through as non-null, so a missing
average threw inside `compositeStats`/`calculateWN8` uncaught, breaking
the page on every load while the bad state persisted in localStorage.

Skip those entries instead of crashing: entries with no tank
definition or no average `mu` are dropped from the delta via
`flatMap`, so the rest of the session table still renders.
