This table used to store majority fee of monero nettype.
By calculating majority fee via "cron" every 300s, the function to
get majority fee for nettypes can be done with single query.
The frontend majority static data in the frontend removed and
now use `/api/v1/fees` endpoint to get majority fee value.
Note: Don't know if it works well with `onload` method or not. Let see.
The administration of the server is done using cli tools. So I don't
think that admin account and module is required. At least for now.
Note that this also remove `tbl_admin` creation in database migrate.
Since no release were made until this commit, the database migration
still in version 1. Manual removal database table for `tbl_admin`
is required on the existing running server.
The log level for the apps is using `log/slog` from Go standard library.
This commit change log format for fiber http logger to match with
the slog standard log format (date and time).
This commit also remove `APP_DEBUG` field from config struct.
TODO:
Use `slog` for default app output. Note that in this commit, the `slog`
output only implemented in `cron` "db migrate" and probe client.
