    fix(web): localize the remaining hardcoded strings on the message page 
(#4633)
    
    `web/src/pages/instance/message.tsx` kept its remaining strings as Chinese 
literals — the default query error, the query-type options, the completion and 
truncation notices, the search button, the pagination `showTotal` — and the 
trace diagnostics behind them were Chinese too, because 
`messageTraceDiagnostics.ts` returned rendered text from the `STATUS_TEXT` and 
`ISSUE_RECOMMENDATIONS` constant tables. An English UI showed both the page and 
the diagnostics dialog untranslated.
    
    The diagnostics interface now returns keys plus interpolation parameters 
instead of text (`titleKey`/`descriptionKey` with `params`, `statusKey`, and 
`recommendationCodes` in place of `recommendations`), the constant tables are 
gone, and `translations.ts` gains 114 new `messagePage.*` keys in both 
languages, 45 of them the per-issue 
`messagePage.issue.<CODE>.{title,description,recommendation}` set. Both 
consumers of the util — the page and its test — moved to the new shape, and the 
Ch [...]
    
    `clientDiagnostics` and `aclRiskDiagnostics`, rendered from `clients.tsx` 
and `acl.tsx`, still carry the same hardcoded Chinese and are left for a 
follow-up.
    
    Fixes #4634
