Refactor DefaultClient from constructor-based to Builder pattern for configurable HTTP client options

[utkrishtsahu]

Changes

Added:

• DefaultClient.Builder class — a new builder pattern API for constructing DefaultClient instances with full configuration control
• connectTimeout(Int) — connection timeout in seconds (default: 10)
• readTimeout(Int) — read timeout in seconds (default: 10)
• writeTimeout(Int) — write timeout in seconds (default: 10)
• callTimeout(Int) — overall call timeout in seconds (default: 0/disabled)
• defaultHeaders(Map<String, String>) — headers included on every request
• enableLogging(Boolean) — toggle HTTP logging
• logLevel(HttpLoggingInterceptor.Level) — granular log level control
• logger(HttpLoggingInterceptor.Logger) — custom logger implementation
• addInterceptor(Interceptor) — add custom OkHttp interceptors
• build() — creates the DefaultClient instance

Deprecated:

DefaultClient public constructor (DefaultClient(connectTimeout, readTimeout, defaultHeaders, enableLogging)) — deprecated with @deprecated annotation and ReplaceWith pointing to the Builder API. Still compiles and functions identically; IDE provides one-click quick-fix migration.

Usage:

val client = DefaultClient.Builder()
    .connectTimeout(30)
    .readTimeout(30)
    .writeTimeout(30)
    .enableLogging(true)
    .addInterceptor(myCustomInterceptor)
    .build()

account.networkingClient = client
