fix(web): align file icon with text in Read/Edit tool rows (#231)

## Summary
The file-type icon after the Read/Edit label sat above the text line.
`.bh-text` aligns children by baseline, and `.tl-ficon` had
`line-height: 0`, so its baseline collapsed to its bottom edge and the
icon rode high. Dropped `line-height: 0` and added `align-self: center`
in ReadTool.vue / EditTool.vue; restaged `dist-web`.

## Testing
- `pnpm run build:web`
- pythinker-web vitest: 85 files / 1012 tests green
