fix(engine): fifteen M19 cards did not match the card that was printed

[ninthworld]

Closes #820. Part of #819.

Diffed all 299 catalog definitions against the real set data — printed characteristics mechanically, ability text by reading each definition beside its Oracle text. Fifteen cards were wrong, and every one passed make check.

Printed characteristics (12)

Card	Field	Was	Printed
dismissive_pyromancer	cost, P/T	{2}{R}, 2/1	{1}{R}, 2/2
enigma_drake	cost	{2}{U}{R}	{1}{U}{R}
gargoyle_sentinel	toughness	3/4	3/3
ghastbark_twins	cost, P/T	{4}{G}, 5/5	{5}{G}{G}, 7/7
goblin_trashmaster	subtypes	["Goblin"]	["Goblin","Warrior"]
goreclaw_terror_of_qal_sisma	cost, P/T	{4}{G}, 4/4	{3}{G}, 4/3
hired_blade	power	2/2	3/2
magistrate_s_scepter	cost	{4}	{3}
marauder_s_axe	cost	{3}	{2}
mistcaller	cost, subtypes, power	{1}{U}, ["Spirit"], 2/1	{U}, ["Merfolk","Wizard"], 1/1
regal_bloodlord	cost, colours, subtypes	{3}{B}{B}, mono-black, ["Vampire","Noble"]	{3}{W}{B}, W+B, ["Vampire","Soldier"]
runic_armasaur	cost, power	{2}{G}, 1/5	{1}{G}{G}, 2/5

enigma_drake prints *; base 0 plus defined_power is the catalog's way of saying that and stays. Only its cost changed.

Costs, amounts, trigger scopes (8)

• dismissive_pyromancer — {R} missing from the draw ability's cost, {T} missing from the damage ability's. The second was activatable while tapped and the turn it landed.
• goblin_trashmaster — a {1}{R} the card does not print. Sacrifice a Goblin is the whole cost.
• ravenous_harpy — cost {B} instead of {1}, plus a gain_life effect the card does not have.
• gift_of_paradise — gained 2, prints 3.
• marauder_s_axe — granted +2/+1, prints +2/+0.
• regal_bloodlord — watched only its controller's end step (prints each), and made a 2/2 (prints 1/1).
• mistcaller — a flash keyword it never had.
• sigiled_sword_of_valeron — the Knight arrived tapped; the card says only "that's attacking", and the token has vigilance precisely so it does not tap.

Tests

The suites asserted against the definitions, so they cemented the bugs. Every one is corrected rather than relaxed:

• issue_740_gift_of_paradise_enchants_a_land_and_gains_two_life → ..._three_life, for a card that gains three.
• m19_mistcaller.rs had a flash test on a card with no flash. Inverted: Mistcaller is now the control that is bound by the sorcery-speed gate, with Hired Blade as the card that isn't. Hired Blade's own file already owns the keyword's positive coverage.
• blocking_an_additional_creature.rs leaned on the Twins being a 5/5 in four assertions. At 7/7 the spread numbers move (3+4 instead of 3+2), and one attacker now dies where it used to survive — which is a better demonstration that the damage-assignment order is load-bearing. Two tests needed an attacker bigger than the blocker to stay meaningful and use Aggressive Mammoth, with the reason stated in each.

Six tests added, stating the printed cost directly — an offer is where a wrong cost is visible, because a missing symbol makes an ability cheaper and cheap is the direction nothing else complains about:

• the Pyromancer's draw ability is not offered off an empty pool, and is off one red
• the Pyromancer's damage ability is not offered while tapped, nor the turn it arrived
• the Trashmaster's ability is offered off an empty pool
• the Harpy costs one generic and gains no life
• the Bloodlord fires on an opponent's end step and makes a 1/1
• the Sigiled Sword's Knight arrives attacking and untapped

What this does not fix

resplendent_angel (a whole ability missing) and skyrider_patrol (two target slots for one printed target) need vocabulary the IR does not have. They are #821.

Nothing here would have been caught by a machine. #822 is the gate that changes that.

make verify green — including e2e-smoke and cargo deny. make compat shows no drift.
