feat(server): register the routes, the slot, the leg and the boot hooks

The entry point becomes real: five mount prefixes, the admin.users.detail
extension slot, the shard push catalog, the town-crier announce leg and both
lifecycle hooks. module.json declares all of it and the loader checks the
declaration against what register() actually registers, in both directions.

The URLs are byte-identical to the ones core served before the extraction. That
is the whole point of moving the code and not the paths: the shipped Android app
calls POST /api/v1/admin/shard/kick and the Discord bot reads
/api/v1/public/shard/*, and neither knows a module answers now.

Require order is load-bearing and the requires are inside register() because of
it. Every ported file reaches core through ./core, whose members resolve ctx
when called -- but a router does `const express = core.express` at ITS file
scope, which runs the moment it is required. Hoisting these to the top of the
file breaks the module with an error about ctx being missing, from a file that
never mentions it.

boot.js takes the eight UO call sites out of core's server.js. One behavioural
change, deliberate: uoLinkSocket.start() and the sidecar health probe used to
run AFTER the listener bound and now run before it, because onBoot does. start()
returns as soon as the reconnecting client is armed, but the probe is a real
HTTP call, so it is fired and NOT awaited -- an unreachable sidecar must not
hold the site closed. Reporting that the bridge is down is diagnostics; being up
is not a precondition for serving a page.

router/rateLimits.js builds the market limiter through ctx.middleware.rateLimit,
core's factory. The policy is the module's -- only the module knows what its
endpoints cost -- and the plumbing is core's, so there is one express-rate-limit
in the process and one place a breach is logged.
