[l10n] ToolsCalcFinalWordScreen: adjusts spacing for locales w/larger fonts

[kdmukai]

Description

Fixes issue identified here: SeedSigner/seedsigner-translations#30 (comment)

Before / After:

---

English (and any other "default" sized font) is unaffected:

---

Changes

• Keeps the bit display font size constant regardless of the body font size of the active locale.
• The middle section ("Checksum") was not ignoring text height below baseline but that was unnoticeable in English since there are no chars below baseline in "Checksum". All the Asian fonts seem to render all kanji chars partially below baseline. Note how the "Checksum" section's bits are now snugged up a bit closer to their accompanying text in the Chinese screenshot.
• Very minor 1-pixel spacing adjustment for locales with larger body font sizes to help avoid having the bottom line run into the button.
