refactor: deduplicate whitelist entries in tts.tsv

Remove entries from tts.tsv that duplicate mappings in alternatives.tsv
(Hon., Mr., Mrs., Ms.) or are self-duplicated Greek letters (κ, ω, α,
ν, δ, Δ, Α, β, Β). This avoids non-deterministic FST behavior across
platforms when the same key maps to different values in unioned files.
