Wrap TX strip controls so CQ isn't clipped in portrait

[patrickrb]

Problem

On a Pixel 8 in portrait, the CQ button was pushed off the right edge of the TX strip and couldn't be tapped (the TX1/TX2 toggle was also clipped).

The TX strip packed six controls into a single non-wrapping Row with Arrangement.SpaceBetween:

[FT4] · [14.080 MHz · 20m ▾] · [DX] · [HUNT] · [CQ] · [TX1] + the status label

Their combined intrinsic width (~445 dp, the frequency pill alone ~180 dp) exceeds the ~411 dp portrait width, so the row overflowed the right edge. The strip got tighter once the FT4 mode pill (#163) and DX/Hound toggle (#162) merged into dev — four controls became six.

Fix

Convert the strip to a FlowRow (the same @OptIn(ExperimentalLayoutApi::class) FlowRow already used in ActiveQsoPanel.kt) so overflow controls wrap onto a second line instead of running off-screen. The six pills are now direct FlowRow children, each centered within its line via Modifier.align(Alignment.CenterVertically), with 8 dp horizontal / 6 dp vertical spacing. The status text is capped to one line so a long localized label can't balloon its row.

• Portrait: wraps to two lines — status · mode · frequency · DX / HUNT · CQ · TX.
• Wider screens: stays a single line.
• No control logic, colors, mutual-exclusion behavior, or callbacks changed.

Verification

Built and installed on a Pixel 8; confirmed in portrait that all six controls are visible and tappable and CQ is no longer clipped:

Before	After
…[HUNT][CQ][T ← TX clipped, CQ at edge	line 1: ● LISTENING FT4 14.080 MHz · 20m ▾ DX line 2: HUNT CQ TX1

This is a declarative Compose layout change with no extractable decision/geometry logic, so there's no new unit-testable surface (the project's tests are JUnit4 + Truth logic tests; Compose layout is verified on-device per CLAUDE.md). The existing unit suite still passes (testDebugUnitTest green).

Pull request overview

This PR adjusts the TxStrip Compose layout to prevent TX controls (notably CQ and the TX1/TX2 toggle) from being clipped off-screen on narrow portrait devices by allowing the control “pills” to wrap onto a second line.

Changes:

• Replaces the single non-wrapping Row layout with an ExperimentalLayoutApi FlowRow so overflow controls wrap instead of running off-screen.
• Adds consistent horizontal/vertical spacing between items and vertically centers each item within wrapped lines.
• Caps the status label to one line with ellipsis to avoid long localized strings expanding the layout vertically.
