This PR fixes the three issues in the nav bar:
1. The GitHub icon was rendered in black in light mode. It should be
white.
2. The toggle theme button's background was white in light mode. It
should be a darker green.
3. The navbar would intersect with the logo due to not compacting
correctly.
The first two issues were caused by using CSS nesting, which is
apparently not supported in Safari yet (and might only be supported if
you have enabled a flag in other browsers).
The last issue was fixed by changing the syntax of a media query. The
new syntax is unsupported in Safari.

## Key Updates in the ADR
- **Separation of Migrations in PRs**: Migrations are now required to be
carried out in separate pull requests. This change is intended to
improve the monitoring and management of database schema changes during
deployment.
- **Primary Key Requirement for New Tables**: A new paragraph mandates
the inclusion of primary keys in all new tables, emphasizing the
importance of data integrity, efficient data retrieval, and supporting
table relationships. Additionally, by adding primary keys, we resolve
the issue of migrations failing during upgrades in replicated database
setups, as we are not using PostgreSQL replica identities. Exceptions to
this rule require a compelling justification.
Also added better structuring and styling to ADR for better readability.
We were sending `user.id` to the service, but if an admin token is used,
there is no `user.id.` Instead, there is
`user.internalAdminTokenUserId`. so we need to use the special method
`extractUserIdFromUser`.
This PR adds this implementation, and now the service correctly
retrieves the appropriate ID for admins.

Added conflict count to CR metrics and CR id.
Something to think about:
There was idea that we can aggregate this data based on CR id, but CR id
is just a number from 0 to x. So it will not be unique across instances.

## About the changes
Schedules a best-effort task setting the value of
events.created_by_user_id based on what is found in the created_by
column and if it's capable of resolving that to a userid/a system id.
The process is executed in the events-store, it takes a chunk of events
that haven't been processed yet, attempts to join users and api_tokens
tables on created_by = username/email, loops through and tries to figure
out an id to set. Then updates the record.
