Fix pasting a valid phone number leaving action buttons greyed out

Covers paste of a valid number, digit-word normalization, typing, and the
/{number} deep-link path — all asserting the action buttons enable.

Paste handling now normalizes digit-word forms with replaceDigitWords and
assigns the bound `value` directly. With svelte-tel-input v4's external
value watcher, validity recomputes from that assignment, so SMS/WhatsApp/
Telegram/contact/QR buttons enable on paste just like on deep-link.

v4 is rune-native and exposes an external value watcher, which the paste
fix for #1 relies on. Rename the removed `normalizedCountries` export to
`countries` in the country pickers. Bump remaining in-range deps and add
@playwright/test for e2e coverage.

TelInput reads input through a use: directive and renders value={inputValue}
one-way, so the old paste handler's synthetic input event never re-ran the
library's validation and `valid` stayed false. Assign the bound `value`
instead, which triggers TelInput's external-value watcher to re-parse and
recompute validity (the same path the /{number} deep-link uses).
