fix(web): reset a tool form by row identity, not by tool name

Copilot review round 4 on #2109. A `tools/list` may repeat a name (#1957) and
ToolsScreen already disambiguates those rows with a key of its own, but the
detail panel handed SchemaForm only the name — so switching between two
same-named tools looked like the same entity and left the first one's enlarged
fields (and its in-progress number/JSON text, which predates this PR) in place.

ToolDetailPanel now takes an optional `resetKey`, defaulting to the name for
callers whose list cannot repeat one, and ToolsScreen passes the row key.
