Include better error handling and messaging for unrecoverable idb error

[fungairino]

Describe the feature

Users will sometimes encounter a "Internal error opening backing store for indexedDB.open" error in various places. We have added retry handling and recovery mechanisms to try to get IDB back to a good state, but in certain cases this error simply isn't fixable by the extension and requires the user to perform some manual debugging steps.

Example user still experiencing this issue: https://app.datadoghq.com/logs?query=issue.id%3Aea6ca0fc-0b23-11ef-ad2c-da7ad0900002%20%40extensionVersion%3A2.1.4%20&agg_m=count&agg_m_source=base&agg_q=%40usr.email&agg_q_source=base&agg_t=count&cols=host%2Cservice&fromUser=true&messageDisplay=inline&refresh_mode=sliding&storage=hot&stream_sort=desc&top_n=10&top_o=top&viz=timeseries&x_missing=true&from_ts=1728413687395&to_ts=1728500087395&live=false
