fix(subscriptions): force uppercase on payment card holder input

[CowboyGH]

Why

The "add card" dialog in Profile auto-uppercases the cardholder name as you type and stores/displays the normalized value. The subscription payment dialog had no such formatter — lowercase input was accepted on screen but fails the ^[A-Z ]+$ validator on submit, and the preview/payload sent raw (unnormalized) text. Two dialogs with the same field behaved differently.

What

• Added _CardHolderTextInputFormatter to subscription_payment_dialog.dart (same formatter as in save_card_dialog.dart) — forces uppercase as the user types.
• Added _normalizedCardHolder getter (trim().toUpperCase()), used for the payment payload and the card preview.

How to test

1. Profile → Subscriptions catalog → open payment dialog → type a cardholder name in lowercase.
2. Confirm it displays in uppercase as you type (both in the field and in the card preview), matching the "add card" dialog in Profile.
3. Submit with a valid card — payment proceeds without a cardholder validation error.
