Update non-major Dependabot dependencies

[djalmaaraujo]

Summary

• combine non-major Dependabot updates for gem and docs dependencies
• update docs Tailwind lockfile to 4.2.4
• add an explicit date stdlib require needed by Phlex 2.4.1 attribute rendering

Included Dependabot PRs

• Supersedes Bump phlex from 2.1.2 to 2.4.1 in /gem #362
• Supersedes Bump rake from 13.2.1 to 13.4.2 in /gem #364
• Supersedes Bump sqlite3 from 2.9.3 to 2.9.4 in /docs #365
• Supersedes Bump standard from 1.41.1 to 1.54.0 in /gem #366
• Supersedes Bump tailwindcss from 4.2.2 to 4.2.4 in /docs #368
• Supersedes Update rouge requirement from ~> 4.2.0 to ~> 4.7.0 in /gem #369
• Supersedes Bump bootsnap from 1.23.0 to 1.24.3 in /docs #372
• Supersedes Bump rake from 13.3.1 to 13.4.2 in /docs #374

Conflict analysis

• gem/Gemfile.lock had overlapping phlex, rake, standard, and rouge changes; this PR resolves them with one Bundler pass.
• docs/Gemfile.lock had overlapping sqlite3, bootsnap, and rake changes; this PR resolves them with one Bundler pass.
• Bump minitest from 6.0.4 to 6.0.6 in /docs #373 is not included here because Dependabot's docs minitest update also changes gem/ruby_ui.gemspec from minitest ~> 5.0 to ~> 6.0, so it belongs with the major-version PR.

Verification

• docker Ruby 3.4.7: bundle exec rake test
• docker Ruby 3.4.7: bundle exec rake standard
• docker Ruby 3.4.7 + Node 20/pnpm 10.8.0: bundle exec standardrb
• docker Ruby 3.4.7 + Node 20/pnpm 10.8.0: bundle exec rails db:test:prepare test
