Add MTU and TTI settings in KCP network (#5539)

Browse Source 
* Add MTU and TTI settings in KCP network

* Rename ProfileItem.tti to kcpTti

Rename the ProfileItem field `tti` to `kcpTti` and update all usages accordingly. Changes update parsing/serialization in FmtBase (map query param "tti" to config.kcpTti and emit it), KCP stream settings mapping in V2rayConfigManager, UI bindings in ServerActivity, and equality checks in ProfileItem to use kcpTti. This clarifies that the field applies to KCP-specific TTI values while preserving the external query key.

* Add kcpMtu/kcpTti for KCP transport

Introduce kcpMtu and kcpTti properties on ProfileItem and update equality checks. Parse and emit KCP-specific mtu/tti in FmtBase (use kcpMtu/kcpTti instead of the generic mtu). Wire kcpMtu into V2rayConfigManager when building KCP stream settings and update ServerActivity to read/write the UI field to profileItem.kcpMtu/kcpTti. This separates KCP MTU/TTI from the general mtu field and removes a duplicated kcpTti entry.
