fix: default suite meta blocks to compact (reading) view

[DavertMik]

Problem

Test meta blocks render compact, but suite blocks stay expanded (see screenshot below). The compact view defaulted to expanded whenever the summary line was empty:

const [expanded, setExpanded] = useState(() => summaryText.length === 0);

summaryText is built only from fields that have a value. Suite blocks commonly carry a seeded field with no value yet (e.g. emoji:), so their summary is empty and they always rendered expanded — while test blocks (populated type / priority / creator) collapsed.

Fix

Base the collapsed-by-default decision on whether the block has any fields, not on whether it has a non-empty summary:

const [expanded, setExpanded] = useState(() => fields.length === 0);

• Any block carrying fields starts compact — suites included, even when the fields have no value yet.
• A genuinely empty block (no fields at all) still starts expanded so it's immediately editable.
• No change to the summary contents, the chevron toggle, or markdown serialization (expanded remains UI-only state).

Testing

• tsc -b — clean
• npm run test:run — 175 passed
• npm run build:package — succeeds
