[eas-cli] Stop spinners from repeating their text after a terminal resize

[szdziedzic]

Why

When you resize the terminal during eas simulator, the "Simulator session active" spinner can print its text again on every frame. The screen fills with copies of the line.

How

eas-cli uses ora 5.1.0. It counts how many terminal lines the spinner text wraps to only when the text changes. It uses that count to clear the previous frame. The simulator spinner text is long and wraps. When the terminal gets narrower, the text wraps to more lines, but the count stays the same. So each frame clears too few lines and leaves one copy behind.

The ora() wrapper in src/ora.ts now recalculates the line count before each frame. It sets the text to its current value, because the text setter does the recalculation. All eas-cli spinners get the fix.

Right after a resize, at most one stale line can stay behind, because the frame on screen was drawn at the old width. After that, the spinner clears correctly.

Test Plan

• Added src/__tests__/ora-test.ts. It simulates a TTY that gets narrower from 200 to 40 columns and checks that each frame clears all 3 wrapped lines. The test fails without the fix (1 line cleared) and passes with it.
• yarn typecheck, yarn lint, and yarn fmt:check pass.
• Manual: run eas simulator, then make the terminal window narrower. The spinner line must not repeat.
