fix(web): remove blurOnTrigger from migration shortcuts

[Roshan1299]

Problem

Migration shortcuts (Ctrl+Cmd+Arrow) in the day view don't work. The shortcuts were registered with blurOnTrigger: true, which cleared document.activeElement before the handler called isFocusedWithinTask(). The focus check always returned false, so migration silently did nothing.

Changes

• Removed blurOnTrigger from the two migration shortcut registrations in useDayViewShortcuts.ts so the handler can read focus state correctly.

Closes #1560

Preserve pending title edits before task migration

If the user presses Ctrl+Meta+Arrow* while renaming a task, removing blurOnTrigger here means the input no longer blurs before handleMigrationNavigation calls onMigrateTask. In packages/web/src/views/Day/hooks/tasks/useTaskActions.ts, title edits live only in editingTitle until onInputBlur/Enter commits them, while migrateTask snapshots the task from tasks immediately; that causes the moved task, undo payload, and persisted move to use the stale title and silently drop the in-progress rename. The existing shortcut tests even cover migration while typing, so this path needs to commit the edit before migrating.
