[test](trx-frontend-http): type the frequency instead of filling it

tune-links drove the dial with Playwright's fill(), which writes a value into the field without a keystroke. The app arms its guard against its own refreshes on the first keydown, so a filled field stays unguarded: any state update landing between the fill and the Enter rewrites the field with the frequency the radio is already on, and the Enter then re-applies that. The window is a few milliseconds wide on a developer's machine and wide enough to lose on a loaded CI runner, where the test failed claiming the tuning had landed on the frequency it started from. Type it the way an operator does: select the field, then send the characters as keystrokes. The select arms the guard before a single character changes. Under CPU throttling that reproduced the failure — 1 in 6 runs with fill(), on this branch and on main alike — typing came through 8 runs clean.
