feat: G15Office job, widget settings and submissions admin, embed.js and the settings importer

- SyncG15Office files each submission as a G15Office task with its screenshot through a fetchguard client limited to the configured host; a River job with 3 attempts, PHP's messages on failure, nothing sent when unconfigured
- the replay of PHP's recorded G15Office exchange (classes/testdata) asserts the task JSON, headers and the screenshot part
- settings screen (cabana field types only), read-only submissions list, manage_settings permission and navigation
- embed.js served byte for byte at /plugins/golem15/feedback/assets/js/embed.js
- feedback:import-settings copies the WinterCMS settings row once
