Offer code cannot be expired

Error message

Offer code cannot be expired

What it means

Raised as `Link::LinkInvalid` when saving a bundle's product settings with a `default_offer_code_id` that resolves to an offer code that is inactive. `OfferCode#inactive?` (app/models/offer_code.rb:314) is true when `valid_at` is in the future (not yet valid) or `expires_at` is in the past (expired). The bundle controller rescues `LinkInvalid` at line 88 and re-renders the form with this message, so nothing is saved.

Solutions

1. Pick a default offer code that is currently active (started and not expired) — reload the offer-code dropdown before saving.
2. Extend the offer code's expiry (or clear its future `valid_at`) on the Offer Codes settings page, then retry the save.
3. If the code should no longer be used, clear the default offer code field (submit a blank id) instead of keeping the expired one selected.
4. As an API caller, verify `!offer_code.inactive?` before sending `default_offer_code_id`; note the form re-sends the current id on every save, so an unchanged id is tolerated (early return) but switching to an expired code is not.

Example fix

# before
patch bundle_product_path(@bundle), params: { product: { default_offer_code_id: expired_code.external_id } }

# after — pre-check the code is active before assigning
offer_code = @bundle.user.offer_codes.alive.find_by_external_id(default_offer_code_id)
if offer_code && !offer_code.inactive?
  @bundle.default_offer_code = offer_code
end

offer_code = @bundle.user.offer_codes.alive.find_by(external_id: default_offer_code_id)
assign = offer_code.present? && !offer_code.inactive? && offer_code != @bundle.default_offer_code
@bundle.default_offer_code = offer_code if assign

def usable_default_offer_code?(code, bundle)
  code.is_a?(OfferCode) && !code.inactive? && code.applicable?(bundle)
end

begin
  update_default_offer_code
rescue Link::LinkInvalid => e
  flash.now[:alert] = e.message # renders form, nothing persisted
end

When it happens

Trigger: POST/PATCH to the bundle product settings form selecting a NEW default offer code (different from the current one — the unchanged-id case early-returns) whose offer code has already expired or is scheduled for the future. Typical flow: seller A creates a code with a 30-day expiry, it lapses, then someone picks it from a stale dropdown months later.

Common situations: Offer code expired between the time the settings page loaded (dropdown populated) and the form was submitted; offer codes created with a future `valid_at` being picked prematurely; multiple admins editing codes so one expires a code another is mid-form on.
