Add an optional `input_prompt` string under [settings] that overrides the default lock/unlock emoji prompt in the input area. When unset, preserve existing behaviour (U+1F512 green for encrypted, U+1F513 red for unencrypted, `> ` red for unknown). When set, use the provided string for all three states. The default emoji prompt can produce stray characters in the input line when iamb runs inside tmux, because ratatui's unicode-width, tmux's internal width tables, and the outer terminal's emoji rendering do not always agree on the width of the lock glyph plus variation selector. An ASCII override avoids the width mismatch without changing defaults.

when running in tmux, the default 🔒/🔓 encryption indicators didnt work properly for me and displayed a comma then a closing parenthesis. i just added the ability to override the input prompt.

Motivation
When running iamb inside tmux, the default emoji prompt can produce stray characters in the input line that only
Ctrl+Lclears.tmux capture-paneon the affected region shows a clean logical buffer — the artifact lives at the terminal display layer, caused by disagreement between ratatui'sunicode-width, tmux's internal width tables, and the outer terminal's rendering of the lock glyph +U+FE0Evariation selector. Not configurable at either end.An ASCII override sidesteps the width mismatch while leaving the emoji prompt intact for users who aren't affected.
