fifa17: give the staging manager the rating the client re-rates it to

The bring-up mints a manager (neither club owns one, and FIFA refuses to start a
match without one). Its catalog entry carried nation/league/team read out of
managercards but not `value` or `rare`, so discard pricing declined for it and
fell back to the placeholder ladder: 150 paid against the 282 the client computes
for itself.

Carry managercards.value 88 and managercards.rare 1, from the same table and with
the same provenance as the fields already there. `rare` is not cosmetic -- it
selects the discard price column, which is the whole difference between 282 and
97.

Both are live-confirmed on the running client: coach_probe grades the manager
record HIT (so +0xb4 == value and +0x58 == rare) and discard_probe reads the
value it computed for itself at +0x3c as 282.

Verified on staging: the manager now quick-sells for exactly 282. With this, every
card the client prices for itself -- manager, GK coach, both fitness coaches --
is paid the number it displays.
