fix: remove timeouts from error toasts so they persist until dismissed (#9543)

## Summary

Remove `life` (timeout) property from all error-severity toast calls so
they persist until manually dismissed, preventing users from missing
important error messages.

## Changes

- **What**: Removed `life` property from 86 error toast calls across 46
files. Error toasts now use PrimeVue's default behavior (no
auto-dismiss). Non-error toasts (success, warn, info) are unchanged.
- Also fixed a pre-existing lint issue in `TaskListPanel.vue` (`import {
t } from '@/i18n'` → `useI18n()`)

## Review Focus

- One conditional toast in `useMediaAssetActions.ts` intentionally keeps
`life` because its severity alternates between `warn` and `error`
