chore: update all dependencies and Ruby to 3.4.10 (#98)

* chore: update all dependencies and Ruby to 3.4.10

Ruby:
- .ruby-version: 3.4.4 -> 3.4.10
- Dockerfile: ruby:3.4.4 -> ruby:3.4.10 (both stages)

Gemspec constraints widened for major version bumps:
- openssl: ~> 3.0 -> >= 3.0, < 5.0 (now resolves to 4.0.2)
- sinatra: ~> 3.1 -> >= 3.1, < 5.0 (now resolves to 4.2.1)
- sinatra-contrib: ~> 3.1 -> >= 3.1, < 5.0 (now resolves to 4.2.1)
- bundler (dev): ~> 2.4 -> >= 2.4, < 5.0 (now resolves to 2.7.2)
- byebug (dev): ~> 11 -> >= 11, < 14 (now resolves to 13.0.0)

Notable resolved updates:
- activesupport/activerecord/activemodel: 8.0.4.1 -> 8.1.3
- rubocop: 1.80.0 -> 1.88.1
- rubocop-rspec: 3.6.0 -> 3.10.2
- rspec: 3.13.1 -> 3.13.2
- itsi: 0.2.19 -> 0.2.27
- solargraph: 0.56.0 -> 0.60.2
- httparty: 0.23.0 -> 0.24.2
- dry-configurable: 1.1.0 -> 1.4.0
- acme-client: 2.0.25 -> 2.0.32
- sqlite3: 2.7.x -> 2.9.5
- trilogy: 2.9.0 -> 2.12.6
- yard: 0.9.37 -> 0.9.44
- jwt: 3.2.0 (via prior dependabot constraint widening)

RuboCop 1.88 introduced Style/YodaCondition as a new cop, which
flagged two comparisons in lib/bullion.rb. Autocorrected by
reversing operand order.

db/schema.rb regenerated by ActiveRecord 8.1.3 (minor formatting
changes from the newer schema dumper).

Verification:
- rubocop: 46 files, 0 offenses
- rake spec: 65 examples, 0 failures
- rake yard: builds successfully

* fix: disable Sinatra 4.x host_authorization for API service

Sinatra 4.x introduced a new host_authorization setting that blocks
requests with unpermitted hosts (defaults to .localhost and .test in
development/test, returns 403 'Host not permitted' otherwise).

Bullion is an ACME API server that should accept requests regardless
of the Host header value. Setting permitted_hosts to [] disables the
host check entirely, matching the pre-4.x behavior.

This caused 38 test failures in CI because rack-test sends requests
with the default host 'example.org', which is not in the permitted
hosts list for the test environment.

* fix: disable host_authorization for Ping service

The Ping service inherits from Sinatra::Application (not Bullion::Service),
so it did not inherit the host_authorization fix from the previous commit.
This caused 2 remaining test failures in CI.
