* feat(design-system): add info semantic color token
Mirrors success/warning/destructive: --color-info maps to blue-600 in
light mode, blue-500 in dark mode. Unblocks the DS::Alert info variant
from carrying a raw 'blue-600' literal in icon_color and lets surface
tokens use bg-info/N alpha modifiers like the rest of the system.

* refactor(design-system): adopt semantic tokens and add body slot in DS::Alert
Replaces the bg-{blue,green,yellow,red}-50 / text-{...}-700 / border-{...}-200
palette block in DS::Alert with semantic alpha-modifier surfaces
(bg-{info,success,warning,destructive}/10 + matching /20 borders).
Drops the 'blue-600' literal that icon_color was returning for the
info variant; helpers#icon now accepts color: :info backed by the
new --color-info token.
Adds an optional title: kwarg and an opt-in block-content slot so
rich alerts (title + paragraph, lists, embedded actions) can render
without callers reaching for a hand-rolled flex layout. The existing
message: API stays backward-compatible — nothing in the codebase that
already calls DS::Alert.new(message: ..., variant: ...) needs to change.
Lookbook gains with_title and with_body_slot examples covering the
new shapes.

* refactor(views): migrate api_keys, hostings, lunchflow alerts to DS::Alert
Cleans up nine bespoke alert blocks that hand-rolled the same
flex + icon + bordered-surface shape DS::Alert already provides:
- settings/api_keys/{new,created,created.turbo_stream}.html.erb — three
near-identical 'Security Warning' / 'Important Security Note' boxes
using the broken bg-warning-50 / text-warning-700 raw-palette pair.
- settings/hostings/{_alpha_vantage,_eodhd,_yahoo_finance,_twelve_data,_provider_selection}_settings.html.erb —
five amber-50 / amber-200 warning boxes covering rate-limit notes,
health-check failure messaging, and the env-configured override
banner. The twelve_data plan-restriction block keeps its bullet
list and pricing link inside the new DS::Alert body slot.
- lunchflow_items/{_api_error,_setup_required}.html.erb — two modal
alert headers whose flex+icon scaffolding now collapses onto
DS::Alert. The surrounding bg-surface 'Common issues' / 'Setup
steps' info cards stay as-is; this PR only touches the alert
shape itself.
No functional or behavioural changes. Locale keys preserved.
amber-* palette uses on the alerts disappear; remaining bg-amber-*
hits in the codebase live outside the alert pattern and stay for
follow-up sub-PRs of #1715.
