Add internal/web/api package with Go structs for every /api/X route:
AdultsResponse, JuniorsResponse, PaymentsResponse, VersionResponse.
All fields carry explicit json: tags matching the Python view-model keys.
Key design choices:
- member_data / month_labels / raw_payments are nested objects (not
the pre-serialised JSON strings used in Jinja templates)
- Expected{Value int; Unknown bool} with custom MarshalJSON emits int
or the string "?" for junior single-attendance months
- RawTransaction covers the full 11-column payments sheet row
schemagen_test.go reflects all four response types via
github.com/invopop/jsonschema and golden-compares against committed
schemas in tests/fixtures/api-schema/. The JSONSchema() method on
Expected lives in the test file so the prod binary has no jsonschema
dependency.

Adds internal/domain/czech.Normalize, the first pure-domain function in
the Go rewrite (M2 milestone). Matches Python czech_utils.normalize byte-
for-byte: NFKD decompose via golang.org/x/text/unicode/norm, drop Mn-
category combining marks (unicode.Mn, not IsMark, to match Python's
unicodedata.combining() semantics), then strings.ToLower.
Includes 13-case table-driven test; all inputs spot-checked against the
Python implementation before locking. Adds golang.org/x/text v0.36.0 as
first external dependency.
