Yuchen Liang 19accfee4e feat(pageserver): integrate lsn lease into synthetic size (#8220 )

Part of #7497, closes #8071. (accidentally closed #8208, reopened here)

## Problem

After the changes in #8084, we need synthetic size to also account for
leased LSNs so that users do not get free retention by running a small
ephemeral endpoint for a long time.

## Summary of changes

This PR integrates LSN leases into the synthetic size calculation. We
model leases as read-only branches started at the leased LSN (except it
does not have a timeline id).

Other changes:
- Add new unit tests testing whether a lease behaves like a read-only
branch.
- Change `/size_debug` response to include lease point in the SVG
visualization.
- Fix `/lsn_lease` HTTP API to do proper parsing for POST.

Logical size + WAL pricing

This is a simulator to calculate the tenant size in different scenarios, using the "Logical size + WAL" method. Makefile produces diagrams used in a private presentation:
