Compile with TypeScript 7

typescript 7.0.2 is the native compiler, so this is a pin and not a second
toolchain. tsc --noEmit on tsconfig.json: 15 diagnostics before and after, the
same pre-existing set on both compilers.

TypeScript 7 checks strictly by default, which surfaced 24 real gaps this
tsconfig had been hiding. No compiler setting moved to quiet them: the query
callbacks in adminAnalytics and adminInvoiceActions now name the row each select
projects, request headers are a Record<string, string> rather than a HeadersInit
that cannot be indexed, an optional amountPaid is checked before it is read, a
quote passes undefined rather than null for its optional columns, and sign-up no
longer probes an identities field that IAM never returns.
