Review round 2. Three findings, all real.
1. Precision. Mantine's `NumberInput` returns the raw *string* rather than
a number once the value reaches `Number.MAX_SAFE_INTEGER` (see its
`isValidNumber` guard), precisely because JS cannot hold it. Parsing
that turned `90071992547409910` into `90071992547409904` and would
have sent the server a number the user never typed. An inspector must
not misreport what it transmits, so such input now reports no value —
which is also what this field did before #1888, so nothing regresses.
Only the integer part overflows, so long decimals stay parsed.
2. `AppDetailPanel` has the same reuse pattern as `ToolDetailPanel`:
`AppsScreen.handleSelect` swaps `selectedAppName` + `formValues` in
place without remounting, so switching between apps with a same-named
number field could retain an equal-valued draft. It now passes
`resetKey` too.
3. An exponent was never reachable: `NumberInput` masks input through
`NumericFormat`, which rejects `e`. Dropped that claim from the doc
comment rather than implying `"1e"` is a case being handled.
