fix: resolve hex input prefix stripping and duplicate template in HexBinDec

- Remove '0x' prefix stripping by updating regexHex to include 'x' character
- Add 'b' character to regexBinary to preserve '0b' prefix
- Implement hexConverter prefix handling for both '0x' and '0X' formats
- Remove duplicate v-dialog template definition (lines 43-84)
- Ensure consistent prefix behavior across binary and hex converters
- All 116 tests pass with changes applied

Closes #982
