48107 frontend [ tasks ] fix forms state

[aicarma-artyom-maslov]

Note

Medium Risk
Touches task completion/revert flows and localStorage draft persistence; incorrect flush/cancel timing could still lose or resurrect draft data, but changes are localized with new tests.

Overview
Fixes task form draft behavior so in-progress output edits are not lost or incorrectly re-saved when the server refreshes task data, the card unmounts, or the user completes or reverts a task.

TaskCard now uses a flushable debounce for localStorage drafts: pending saves are flushed before output is reloaded from the server or on unmount, and cancelled on complete/revert so stale drafts are not written back. Output field keys are scoped with task.id to avoid collisions when switching tasks. On revert, the action includes clearOutputTaskIds for the current task and its revert chain.

localStorage helpers gain bulk draft removal and drop the storage key when no drafts remain.

ExtraFieldFile refreshes the displayed attachment list when props change (unless an upload is in progress) and merges new uploads against the latest file state via a ref.

Tests cover debounce flush/cancel, storage cleanup, draft persistence edge cases, and file-field sync during upload.

Note

Fix task form state to prevent draft loss and stale data on revert or complete

• Replaces throttle-debounce's debounce with a new createFlushableDebounce utility that supports explicit flush and cancel, so pending draft saves can be controlled at key moments.
• TaskCard flushes pending saves when task output data changes or on unmount, and cancels pending saves before completing or reverting a task.
• On revert, setTaskReverted now accepts clearOutputTaskIds to remove drafts for the current task and related revert tasks in a single localStorage operation.
• ExtraFieldFile uses a ref to track files-in-flight so uploads and deletions always operate on the latest file list even if props change mid-upload.
• saveOutputsToStorage now removes the localStorage key entirely when no drafts remain instead of storing an empty array.
