Add P7 management-control tools behind a single McpManage flag (plus
McpReadonly=0): kill_process, operate_window, control_service and
power_action. The write tools run a ready->confirm lifecycle on their
sub-connection, using a new followUp/followUpSent field to tell the two
arrivals of the same TOKEN_*LIST apart; the write command and the follow-up
refresh command go out as two separate Send2Client calls, with a new
WaitSendIdle() (context.h / Server.h) draining the outbound buffer in between
so the same buffer is never WSASend'd concurrently.
McpSettingsDlg gains a "management operations" checkbox (IDC_MCP_MANAGE), the
main toolbar gains an MCP entry button, and en/de/zh-TW strings are synced.
power_action is fire-and-forget over the main connection (no confirmation).
Verified end-to-end against a real Windows 10/VMware client: kill_process
returns remaining:[] and operate_window/control_service return ok:true with
their confirm packet arriving after an HTTP split. Verification surfaced a
prerequisite parser bug, fixed separately in a72e6eb, where HeaderParser
latched m_bShouldUnmask FALSE on HTTP continuation chunks and dropped the
confirm packet.

Add a 15th toolbar button "Lang/语言" after the Help button so Chinese
readers can switch language without knowing English; it opens the existing
language-select dialog. The dialog title is now bilingual ("切换语言 /
Switch Language") and its label/buttons use Chinese source strings
("语言:", "确定", "取消"), which still localize to en/de via
TranslateDialog. The toolbar bitmap is extended with a globe icon.

Add 16x16 icons for the three context-menu items that previously had
none: "Activity History" (Client Management), "Browse Window" (Remote
Control), and "Proxy Port - Auto Start" (Client Proxy). Register three
new bitmap resources and extend the main dialog's bitmap array from 63
to 66 entries so each menu item renders an intuitive glyph.
