fix(persona): the lines go behind the boxes, and one thing looks pressed

[stormer78]

Three things from a live testing pass, in the order they were hit.

The edges were drawn over the cards

The SVG is positioned and the bands were not, so it won a stacking contest nobody entered it into: every curve ran across the boxes it connects, through the type and the value. The bands are positioned now with a higher zIndex.

An edge that disappears under a card reads as going behind it, which is what it does.

Everything a selection reached looked selected

"The UX is a little clunky — I can't easily tell what I have clicked on. I clicked on the persona DID, but how can you tell?"

Both the pressed card and everything it reached wore a coloured border, so clicking one persona outlined its face, three attributes, its context and the context's row in the same treatment. A dozen outlined boxes and no way to tell which one was the question.

The two states stop competing:

	before	after
selected	2px accent border + soft halo	2px accent border + a ring: a hairline of the page's ground, then the accent
reached	1px coloured border + wash	wash only, ordinary border

One outline on the screen, and it is always the thing you pressed. The ring is two-stage so it lifts off a band that is already tinted, where a single soft halo disappears. The persona row inside a context gets the same rule — it is the one people click most, being where who am I here is asked.

A withheld value lost its own sentence

Singapore · with your agent does not fit a 222px card and truncated to Singapore · with y… — dropping the half that says what to do about it.

The label steps aside while the value is absent. It is the holder's own note, the type above already names the attribute, and on a card holding nothing the sentence that matters is the one about where the value is. It returns the moment the value does.

Checks

367 extension tests pass; tsc -b and npm run build clean.

⚠️ CI on this PR will show three failing core tests that are not from this change. 220560e feat(core): a rooms API for the console was committed straight to main and leaves package.module-boundaries and task-surface red — see the comment below.
