feat(i18n): translate the log levels, access events and calendar labels (#6226)

* feat(i18n): translate the log levels, access events and calendar labels

The log-level selector, the access-log event tags, the Sub Formats sidebar
entry and the calendar choices were hardcoded English, so a fully translated
locale still showed them in English on core screens.

Add eleven keys across the 13 locales and reference them. Russian and
Ukrainian are translated; the remaining locales carry the English string, the
same convention the existing files already use for untranslated entries.

Two module-level constants had to move: the calendar list and the access-event
map were built outside the component, where t is not in scope. The event map
now stores keys and resolves them at render.

* fix(i18n): keep the log export language-independent and fit the translations

Three follow-ups from review. The downloaded x-ui.log had started carrying the
translated event text, so its contents depended on the panel language and the
Russian value for PROXY contains a space in a field format whose other values
are single tokens. The export keeps DIRECT/BLOCKED/PROXY; only the on-screen
tag is translated.

The log-level select had a fixed 95px width sized for "Warning", which clips
"Предупреждение"; it now grows with its content.

The three access filters stayed English while the tags they filter became
translated, so they use the same keys.
