build(deps): bump aw-tauri and aw-qt to pick up the start-at-login toggles

[TimeToBuildBob]

Both autostart PRs merged today; this bumps the bundle pins so the next release actually ships them (dependabot's gitsubmodule schedule is monthly).

Submodule	From → To	Carries
aw-tauri	1aa54bf → f70bcdf	ActivityWatch/aw-tauri#238 — "Start at login" tray toggle + get/set_autostart_enabled
aw-qt	6fbb5f7 → 45f4c2f	ActivityWatch/aw-qt#127 — user-toggleable OS login item (per-OS backends)

Exactly one commit per submodule between the old and new pin (compare checked), nothing else rides along.

Greptile Summary

This PR advances the two alternative desktop-shell submodules to revisions that include user-facing start-at-login controls.

• Updates aw-qt from 6fbb5f7 to 45f4c2f.
• Updates aw-tauri from 1aa54bf to f70bcdf.

Confidence Score: 5/5

The PR appears safe to merge because the reviewed changes only advance the two existing desktop-shell submodule pins and no concrete blocking or non-blocking defect was established.

Both desktop-shell pins remain integrated through their existing mutually exclusive build paths, and the available evidence identifies no changed top-level contract or reachable failure.

Important Files Changed

Filename	Overview
aw-qt	Advances the default Qt desktop shell to the revision carrying its OS login-item toggle; no concrete integration defect was established.
aw-tauri	Advances the Tauri desktop shell to the revision carrying its start-at-login commands and tray toggle; no concrete integration defect was established.

Greptile is 5/5 and found no issues. The cross-platform build matrix is still running, so there is no code action to take yet; waiting for CI and maintainer review.
