[onelink] Clean up use of interpolated brand strings

[mindy-stripe]

Summary

Need to get latest strings for these values:

In paymentsheet/res, the missing branded strings are:
stripe_sign_out_with_brand
Present only in base paymentsheet/res/values/strings.xml:273. Missing from every localized paymentsheet/res/values-*/strings.xml file, i.e. all 40 locale directories:
b+es+419, ca-rES, cs-rCZ, da, de, el-rGR, en-rGB, es, et-rEE, fi, fil, fr-rCA, fr, hr, hu, in, it, ja, ko, lt-rLT, lv-rLV, ms-rMY, mt, nb, nl, pl-rPL, pt-rBR, pt-rPT, ro-rRO, ro, ru,
sk-rSK, sl-rSI, sv, th, tr, vi, zh-rHK, zh-rTW, zh.

paymentsheet/res/values-zh-rTW/strings.xml
This locale is also missing these 9 branded keys:

• stripe_pay_with_link_with_brand
• stripe_sign_up_terms_alternative_with_phone_number_branded
• stripe_sign_up_terms_alternative_branded
• stripe_sign_up_terms_branded
• stripe_sign_up_terms_default_opt_in_branded
• stripe_inline_sign_up_header_default_opt_in_with_brand
• stripe_inline_sign_up_toggle_with_brand
• stripe_link_sign_up_message_v2_with_brand
• stripe_paymentsheet_card_mandate_signup_toggle_on_v3_branded

Everything else from the target _with_brand / _branded set is present in the other locales. The practical blockers are:

• stripe_sign_out_with_brand for the logout menu cleanup everywhere
• the 9 zh-rTW misses for the remaining LinkButton, LinkTerms, and inline-header cleanup paths

Motivation

Testing

• Added tests
• Modified tests
• Manually verified
