Show complete proposal summaries in uniform cards

[Cyber-preacher]

Why

Proposal cards shortened summary strings in JavaScript and then clipped them to one CSS line. Complete descriptions such as the Ember proposal were therefore invisible, while allowing unrestricted wrapping would make card heights inconsistent.

What changed

• preserve the complete normalized summary in the shared GlassyRecordCard
• place summaries in a full-width responsive row with stable card geometry
• reserve consistent title and summary regions across desktop, tablet, and mobile
• retain contained scrolling only for exceptional legacy text beyond the reserved region
• add regression coverage for complete summary rendering and the stable layout contract

Because this is implemented in the shared record card, proposal lists, chamber records, Feed records, and public drafts use the same behavior.

Validation

• yarn test - 54 files, 240 tests passed
• yarn typecheck
• yarn build
• Prettier and git diff --check
• browser verification against all 13 public production proposals at 390, 768, 1024, and 1440 CSS pixels: equal card heights with no title or summary overflow

Data safety

Web-only presentation change. No API contract, migration, runtime mock wiring, production data, or preview artifact is included.
