✨RUM-16635 Add wildcard host pattern matching to WebView event bridge

[barboraplasovska]

Motivation

Part of RUM-15826. iOS SDK counterpart DataDog/dd-sdk-ios#2963.

Changes

Adds a new optional getAllowedWebViewHostPatterns?() method to the DatadogEventBridge interface. When present, canUseEventBridge() uses wildcard pattern matching via plain string operations instead of the legacy exact + subdomain-suffix path.

Invalid patterns (more than one *) produce a display.error console warning so customers see an actionable signal. Old Browser SDK versions receiving wildcard entries from a new mobile SDK will silently ignore them (literal match fails) while plain host entries continue to bridge normally.

Test instructions

CI should pass.
