Respect IDE Proxy Settings in IntelliJ Plugin

[icycodes]

Currently in the IntelliJ plugin, the chat panel webview already respects the IDE's proxy settings. While the proxy settings for tabby-agent is retrieved from ~/.tabby-client/agent/config.toml and falls back to using system environment variables. It would be good for tabby-agent to also respect the IDE's proxy settings.

Reference: tabby-agent protocol.ts#L215

Example on how vscode pass proxy settings to agent:

tabby/clients/vscode/src/Config.ts

Line 170 in b068388

proxy: {

IntelliJ code building the client provided config:

tabby/clients/intellij/src/main/kotlin/com/tabbyml/intellijtabby/lsp/ConfigurationSync.kt

Line 39 in b068388

fun getConfiguration(): ClientProvidedConfig {
