fix: inline connector dot alignment for tooltip-above-target

[aldefy]

Summary

Fixes inline connector dot misalignment when titleInlineWithConnector is enabled and the tooltip renders above the target. Previously, inline mode only activated for tooltip-below; now it supports both directions.

Before / After

Scenario	Before	After
Tooltip below target	Dot renders at top of tooltip, inline with title. Connector draws from cutout → dot	No change — same behavior
Tooltip above target	Inline mode disabled. Dot drawn on canvas at targetCenter.x, misaligned with title	Inline mode active. Composed dot renders at bottom of tooltip Column, aligned with content start. Connector draws from cutout → measured dot position

Key behavioral differences (tooltip-above):

Before:

• isInlineTitleActive was false — fell back to canvas-drawn dot
• Canvas dot at targetCenter.x didn't match title text position
• Connector ended at a generic point below the tooltip

After:

• isInlineTitleActive is true for all vertical connectors
• Composed dot at bottom of tooltip, aligned with content left edge (connectorDotOffsetX = 0.dp)
• Connector line draws from cutout edge directly to the measured dot center

Changes

Internal

• CoachmarkTooltip.kt: Added isTooltipBelow parameter. When below → existing top Row (dot + title). When above → title renders normally, bottom Row with dot added after footer
• CoachmarkScrim.kt: Removed && isTooltipBelow gate from isInlineTitleActive. Extracted isTooltipBelow to outer scope. Passed through TooltipContainer → CoachmarkTooltip. Set connectorDotOffsetX = 0.dp for above case

Breaking Changes

None

Platform Support

• Android
• iOS
• Desktop (JVM)
• Web (Wasm)

Testing

• ./gradlew :lumen:compileKotlinJvm (commonMain)
• ./gradlew :sample:assembleDebug (sample app)
• Manual testing on device/emulator — set titleInlineWithConnector = true on a target where tooltip appears above, verify dot at bottom aligns with connector

Release Notes

Features

• Inline connector dot now aligns correctly when tooltip appears above the target
