ADFA-3641: Wire per-task tooltips for Gradle tasks (#1519)

* ADFA-3641: Wire per-task tooltips for Gradle tasks

Each task row in the Run-Tasks dialog now shows its own tooltip instead of a
single generic one. The tag is derived from the task path
("gradle." + path.removePrefix(":")), matching the authored content keys
(":app:assembleDebug" -> "gradle.app:assembleDebug", ":clean" -> "gradle.clean").

- TooltipTag.gradleTaskTooltipTag(): pure path->tag mapping (unit-tested).
- RunTasksListAdapter: use the per-task tag instead of PROJECT_GRADLE_TASKS.
- ToolTipManager.getTooltip: honor its nullable contract - return null on a
  missing tag so uncovered tasks show no popup instead of an "n/a" tooltip.
  No fallback.

Tooltip content lives in the SoT documentation.db (loaded separately).
Verified end-to-end on the emulator: per-task Tier-1/2 tooltip + Tier-3 help
page, and graceful no-popup for tasks without authored content.

* ADFA-3641: spotlessApply on touched idetooltips files

Stage now runs spotlessCheck in CI (ADFA-2522). Spotless' ratchet is
file-level, so the two files this branch touches get reformatted
whole-file (space -> tab). Whitespace-only; no logic change.

* ADFA-3641: rethrow CancellationException in getTooltip

A broad catch(Exception) in the getTooltip suspend function swallowed
coroutine CancellationException, silently returning null (a "no tooltip"
result) on cancellation. Rethrow it before the fallback catch to keep
structured concurrency intact.
