Fix gate card visibility, add 5 missing tool SVGs, update pricing to EUR 4-tier

Gate cards: remove .lt-gate__card from paper-card override so dark navy
backgrounds restore; drop blue title colour override for gate cards.

SVGs: add translate (bilingual doc), citations (citation graph), korrespond
(formal letter), summarize (doc→extracted bullets), legal-analysis (issue
sections + dbn-legal-agent-v3 badge).

Pricing: 3 NOK tiers → 4 EUR tiers (Free €0 / Light €9 / Pro €29 / Pro+ €79);
Pro+ is new; "Plus" references updated to "Light" throughout.
