management is not affected.

Users who have their system clocks configured inconsistently due to Daylight
Savings may see a GitLab session cookie that immediately expires, resulting in
a 422 error. To avoid these errors, we can bump the unauthenticated session
time from 1 hour to 2 hours so they have time to login and get the default 7-day
session.

Closes #50393

By default, all sessions are given the same expiration time configured in the
session store (e.g. 1 week). However, unauthenticated users can generate a lot
of sessions, primarily for CSRF verification. It makes sense to reduce the TTL
for unauthenticated to something much lower than the default (e.g. 1 hour) to
limit Redis memory. In addition, Rails creates a new session after login,
so the short TTL doesn't even need to be extended.

Closes #48101

This adds a recurring Sidekiq job that removes up to 50 000 old web hook
logs per hour, if they are older than 90 days. This will prevent the
web_hook_logs table from growing indefinitely.

Also, refactor the mail sending slightly: instead of one worker sending all
emails, create a worker per project with issues due, which will send all emails
