[Task]: Replace remaining `basic` intents with `support` once basic is removed

[soulcramer]

Outcome

All basic intent usages in the Android codebase are replaced with support after the basic intent family is formally removed.

Problem

Android must replace all remaining basic intents with support as part of the rebranding, but basic has not yet been removed. This issue tracks the final removal step and is blocked on design confirming the basic family will disappear. Raised by J.B. on 2026-03-19 in #lbc-spark-x-teamui.

Context

The migration from basic to support is largely complete. The remaining work cannot proceed until the design team formally signs off on removing the basic intent family. This issue is blocked until that sign-off is given.

Scope

• Replace all remaining basic intent usages with support once basic is formally removed

Acceptance criteria

• No basic intent references remain in the Android codebase
• All previously basic components render correctly using support
