Attendee summary view

[LeHack]

This view is the only one the training attendees should see after logging in (all other views should be admin-only).
It should contain:

• the current balance
• last 5 payments made (with "Show more" button)
• current month attendance stats (training count and a percentage) separated into basic and extra (attendance to the assigned group, attendance to other groups) - sort of a "Progress status"
• attendance stats for the last 5 months (similar to the above, but below and in a smaller font)

ℹ️ Note: in order to count the percentages we need to know how many trainings there are to be in a month, so this will require #9 to be completed, thus this part is a "Could have" not "Must have"
