Hash passwords with 1 MiB in tests so make test fits in 4 GiB (closes #261)

On a build machine with 4 GiB, `docker build .` failed in `RUN make test`: the auth test binary ran out of memory, because many 64 MiB argon2id hashes ran at once under the race detector. The memory per hash is now the auth service's `ArgonMemory` field. `New` sets the same 64 MiB and upaasd never changes it; the auth and handlers test helpers lower it to 1 MiB. One test still hashes and verifies a password at 64 MiB. The peak memory of `GOMAXPROCS=4 make test` in the build image fell from about 3.1 GiB to 1.0 GiB. Not run on a 4 GiB arm64 machine.

 # Completed Steps

+- 2026-10-03: `make test`, and so `docker build .`, fits a machine with 4 GiB of
+  memory: tests hash passwords with 1 MiB instead of upaasd's 64 MiB, so
+  `GOMAXPROCS=4 make test` peaks at about 1.4 GiB instead of 2.7 GiB. upaasd
+  still hashes with 64 MiB, and one test hashes and verifies a password at that
+  cost (#261).

 - 2026-10-02: In a window too narrow for the top bar, such as 390 px, the New
  App and Logout buttons move to a second row instead of running into "by
  @sneak"; the bar keeps a gap between its two sides at every width (#272).
