fix(android): pin TextView line-breaking to match measurement [SUP-1472]

[xindixu]

Description

On Android, long / citation-heavy markdown messages were rendered truncated — the last paragraph(s) clipped — while identical content rendered in full on iOS and Web.

Root cause: a measure-vs-render line-breaking mismatch. MeasurementStore builds a StaticLayout that sets breakStrategy = HIGH_QUALITY only on API 29+ and leaves hyphenationFrequency at the default (NONE). The rendered TextView (setupAsMarkdownTextView) set neither, so it fell back to platform defaults (hyphenation enabled; HIGH_QUALITY even below API 29). The two paths wrapped text differently, so the rendered text used more lines than the measured height reserved for the view — and since a TextView clips overflow instead of scrolling, the tail was cut off. Same class of bug as the earlier Android width-clipping fix, on the line-breaking axis.

Technical detail

• utils/text/view/TextViewSetup.kt: pin the rendered TextView to BREAK_STRATEGY_HIGH_QUALITY + HYPHENATION_FREQUENCY_NONE on API 23+ (covers both EnrichedMarkdownText and EnrichedMarkdownInternalText, which share this setup).
• MeasurementStore.kt: extract applyMarkdownLineBreaking() and apply it to all three StaticLayout builders, extending the same settings down to API 23 (previously HIGH_QUALITY was set only on API 29+, so on API 23–28 measurement used SIMPLE while the TextView rendered HIGH_QUALITY).

Result: measure == render on every API level.

Test Plan

• Rebuilt the Android app; the previously-truncated citation-heavy message now renders in full, matching iOS and Web.
• Spot-check other markdown (headings, lists, tables, code blocks, long links) for correct height on Android.
