fix(cua): show call titles and align app icons

[Yash-Singh1]

CUA tool calls displayed Cua_repl.js instead of the action title supplied to the tool. Native app icons also looked too small and sat high in the activity row.

Use the CUA title argument when projecting new calls and when rendering existing saved calls in web and mobile. Center tool icons in the row and size native app icons to match the surrounding text. Desktop uses the web timeline.

Approvability

Verdict: Approved at 9d2f934

Macroscope's review found this PR approvable — This is a narrowly scoped CUA display fix with focused tests: it populates and renders action titles while preserving existing fallbacks, and adjusts icon alignment and sizing. It does not alter tool execution, product defaults, schemas, or sensitive infrastructure.
