Christian Byrne 71ca582325 fix: reset file input value after selection to allow same-file reupload (#11417)
*PR Created by the Glary-Bot Agent*

---

## Summary

Fixes the "choose video to upload" button becoming unresponsive after
running a workflow with a subgraph a few times.

**Root cause**: The detached input element in `useNodeFileInput` never
resets its `value`. The browser's `onchange` only fires when the value
*changes* — re-selecting the same file silently drops the event. A page
refresh recreates the input with an empty value, which is why refreshing
fixes it.

## Changes

- `useNodeFileInput.ts`: Reset `fileInput.value` before invoking
callbacks so value is cleared even if a callback throws
- `useNodeDragAndDrop.ts`: Add `onRemoved` cleanup for installed
handlers (only clears own handlers; preserves replacements from
extensions)
- `useNodePaste.ts`: Add `onRemoved` cleanup for installed `pasteFiles`
handler (same reference-safe pattern)
- 3 new colocated test files with 26 test cases covering all branches

## Codebase Audit

Audited all 11 file upload implementations across the codebase. Found 5
using the ghost/virtual input pattern — 3 with the same missing
value-reset bug:
- `useNodeFileInput.ts` — fixed in this PR
- `scripts/utils.ts` (`uploadFile()`) — one-shot pattern, lower risk
- `extensions/core/load3d.ts` — partial reset only

The 4 Vue component implementations already reset correctly.

## Future Work

VueUse `useFileDialog` composable handles same-file reselection via
`reset: true` and provides automatic lifecycle cleanup. A follow-up PR
could migrate the ghost input patterns for a centralized solution.

## Test Plan

- 26 unit tests across 3 new test files (all pass)
- 9 existing useNodeImageUpload tests still pass
- Pre-commit hooks pass (oxfmt, oxlint, eslint, typecheck)
- Oracle code review addressed
