M2a: server workspace, kvitt-domain, skeleton routes, OpenAPI match, Dockerfile

Cargo workspace (kvitt-domain, kvitt-server, kvitt-import), Rust 1.99.1 pinned.
kvitt-domain passes every Rust vector and adds next_occurrence_date (D-015).
kvitt-server: config, SQLite pool (WAL, §8.9 pragmas), migration 0001 identical to
the contract schema, error type for all 25 codes, auth extractor and protocol
layer, all 33 routes (E-1/E-2 implemented, the rest 501), utoipa document equal
to contracts/openapi.yaml, seams for M3/M4/M9, serve/migrate/healthcheck.

//! The utoipa document equals `contracts/openapi.yaml` (SPEC §14.3, §11.2 M2a).
//!
//! Both documents are parsed into JSON values and brought to one canonical form before comparing. The comparison
//! fails on any added, missing or differently typed field, path, operation, parameter, request body, response,
//! response header, security requirement or enum value. The normalisations, all of which are representational (they
//! do not change what a client may send or will receive):
//!
//! 1. Key order: JSON objects are compared as maps.
//! 2. `$ref` naming and placement: every local `$ref` is replaced by the (normalised) value it points to, so it does
//! not matter whether something is a named component or inline, or what the component is called. Sibling keys
//! next to a `$ref` override the target's (OpenAPI 3.1 Reference Object). Discriminator `mapping` values are
//! references too and are resolved the same way. Components that no operation reaches are compared by name.
//! 3. Documentation text: `description` and `example`/`examples` keywords are dropped everywhere (property *names*
//! called `description` are kept). Operation `summary` and `operationId` are compared.
//! 4. Nullable spellings: `type: [T, "null"]` is rewritten to `oneOf: [{type: T, …}, {type: "null"}]`; nested
//! `oneOf`s are flattened and their members compared as a set (order of alternatives carries no meaning).
//! 5. `const: v` is rewritten to `enum: [v]` with the JSON type of `v`; `enum` values and `required` lists are
//! compared as sets.
//! 6. Defaults written out or left implicit: `required: false` and `deprecated: false` are dropped; a path parameter
//! is always required.
//! 7. Parameters are compared as a set keyed by `(in, name)` (their order carries no meaning).
//! 8. Security: each operation carries its effective requirement (its own `security`, or the document's); the
//! document-level key itself is then dropped.
