* fix(a11y): announce the MCP server value and name the key/value pair inputs

Two defects QA found on this PR.

The MCP server trigger is a plain button, not a combobox: a screen reader
announces its name and nothing else. Labelling it with the field alone
meant aria-labelledby won the name computation and the selected server was
discarded, so users heard "MCP Server" with no value. Compose the field
label and the visible value span into the name instead, and drop the
aria-label that used to carry the value on its own.

The key/value pair field labelled only its key input, leaving the value
input announced as a bare "edit text" and indistinguishable from the key
beside it. Name it from the field label plus a translated qualifier, so
the pair reads as "<field>" and "<field> value".

* fix(a11y): name every key/value row, not just the first

Naming only the first row left every later row announced as a bare
"Type a value..., edit text" — the same symptom QA reported, one row down,
and an axe `label` violation on both inputs of each additional row.

Every row is named now. Rows past the first carry their position, so they
stay distinguishable from row 1 and from each other: "Headers",
"Headers value", "Headers row 2", "Headers value row 2".

This reverses the first-row-stands-in-for-the-field rule this component
borrowed from inputListComponent. That rule leaves real controls unnamed,
which is a Level 1 failure; inputListComponent still has it and needs the
same treatment separately.
