fix(i18n): add missing multi_tab translation keys to en.json

PR 4: fix(i18n): add missing multi_tab translation keys to en.json

Description:

The multi-tab warning modal (MultiTabModal.ts) renders copy using translateText() calls for the multi_tab.* namespace (multi_tab.warning, multi_tab.detected, multi_tab.please_wait, multi_tab.seconds, multi_tab.explanation).

However, the multi_tab key section was missing from resources/lang/en.json, causing the modal to render raw translation keys on-screen instead of localized text.

This PR adds the missing multi_tab translation key object to resources/lang/en.json in alphabetical order, resolving the modal's copy and satisfying EnJsonSorted.test.ts.

Please complete the following:

• I have added screenshots for all UI updates (N/A — i18n text resolution)
• I process any text displayed to the user through translateText() and I've added it to the en.json file
• I have added relevant tests to the test directory (tests/client/MultiTabModal.test.ts)
• I confirm I have thoroughly tested these changes and take full responsibility for any bugs introduced

Please put your Discord username so you can be contacted if a bug or regression is found:

Poem

One tab stays bright,
While others wait in quiet light.
Strings guide the way,
Tests guard each phrase today.
Vigilant mode holds tight.
