Add a per-client TLS transport toggle controlled from the server, using the
presence of the client's trust-anchor certificate in the registry as the
single source of truth (no separate tls_enable flag).
- Client reports its TLS status via a new RES_TLS token (cert present -> 1)
appended to LOGIN_INFOR's reserved field.
- Server online list gains a "TLS" column after the permission column.
- The "experimental features" right-click menu gains "TLS传输" / "取消TLS"
with confirmation and a guard that prompts (instead of sending) when the
server has no TLS certificate ready.
- New COMMAND_TLS_ENABLE / COMMAND_TLS_DISABLE (166/167): the server pushes
its cert PEM into the client registry settings\tls_cert (enable) or deletes
it (disable). The client picks this up on next startup via the existing
ReadTrustAnchor logic, so the switch is non-live by design.
- Icons and en_US/zh_TW/de_DE translations for the new menu items.

Cloned miniPC images share the same MachineGuid, so their client_id
collides and only one host appears in the list. Fold the hostname into
the V2 client-ID hash so hosts with distinct names no longer collide.
Already-persisted client IDs are unchanged: they recompute only after
the settings/client_id registry value is cleared.
Server side, when a login reuses an existing client_id but the hostname,
IP, or username differs, emit a WARN diagnostic before assigning the
connection to the standby list. Observation-only, no behavior change.

Geographic location (city, country) from the geo APIs is UTF-8, but the client
and several server paths converted or stored it in the system ANSI code page,
turning umlauts ("ö"/"ä") into "?" or GBK mojibake ("B枚blingen"). Keep the
value UTF-8 end to end: the client caches it as UTF-8 and re-queries once after
an upgrade (keyed by __DATE__, the app's version convention), while the server
stores and displays it as UTF-8 in the online list, the activity log, the
client-info export, JSON/email payloads and search.
Also add a confirmation prompt before opening a remote chat from the toolbar,
with German, English and Traditional-Chinese translations.
