chore(deps): lift driver-turso's new tsx devDependency to ^4.23.15 and regenerate the lockfile

Main's driver-turso change added `"tsx": "^4.23.12"` with a lockfile
importer at 4.23.12, while this branch lifts tsx to ^4.23.15 everywhere
and drops the tsx@4.23.12 entries. The two lockfiles merged as text into
one that `pnpm install --frozen-lockfile` refuses
(ERR_PNPM_LOCKFILE_MISSING_DEPENDENCY: no entry for 'tsx@4.23.12'),
reproduced locally on the merge commit. The new declaration takes the
same lift, and the lockfile is regenerated with `pnpm install
--lockfile-only` (pnpm 10.31.0), never edited by hand: a fixed point,
frozen install passes, one tsx copy (4.23.15) for all 27 declarations,
and no resolved version goes down against main e35c40a.

The regeneration also returns packages/apps/account's vitest snapshot to
the esbuild 0.28.1 peer variant main carries, undoing the dedupe an
earlier `pnpm update` on this branch had made there.
