i18n(ru): refine Russian localization against the zh-Hans source (#9431)

* i18n(ru): refine Russian localization against the zh-Hans source

Translate newly added UI strings and align existing Russian entries
with the authoritative Simplified Chinese (zh-Hans) source, since the
project is maintained by a Chinese-speaking author.

New strings (check-for-update flow):
- MsgCheckUpdateHasNewVersion, menuCheckOnly, menuNewUpdate,
  MsgNotSupport, LvTestIpInfo

Correctness fixes (changed meaning):
- TbSettingsHysteriaBandwidth: restore upload/download order (Up/Dw)
- TbSettingsMixedConcurrencyCount: "multi-threaded" (was "multi-stage")
- TransportRequestHostTip4: "QUIC encryption method" (was "security")
- TransportPathTip3: "QUIC encryption key"
- TbDomesticDNS: "DNS for direct connections"

Terminology and clarity:
- Unify the alias field to one consistent term across all rule/profile
  labels, distinct from the memo field
- allowInsecure -> "skip certificate verification" (+ cert-pinning ref)
- Restore details dropped from EN but present in zh-Hans: Port Hopping
  range, pre-SOCKS split routing, optional / "may fail" hints

Consistency and cleanup:
- Orthography, transport names (httpupgrade, XHTTPObject),
  move-to-top/bottom wording, trailing-space cleanup

Scope: ServiceLib/Resx/ResUI.ru.resx only. Technical abbreviations are
kept in English (LAN, UUID, MTU, TLS, ALPN, SNI, ...). Stale Chinese
strings vs. current behavior were judged case by case.

* i18n(ru): shorten update-check button labels to fit fixed-width buttons

The check-update window has two fixed-width (100px) buttons. The Russian
labels were faithful but too long, so both were truncated and looked almost
identical, hiding the difference between the two actions:
- the "Only Check" button only checks whether a newer version is available
- the "Check Update" button checks, downloads, installs and restarts

Shorten both so they fit the button and clearly distinguish check vs update.

Note: menuCheckUpdate is also reused as the default row placeholder in the
update list, which now shows the shorter label as well.
