feat (UI): add mixture components table with calculations

- add select sample type dropdown
- add component table header
- add liquid components section
- add liquid components calculations
- add solid components section
- add solid components calculations
- drag and drop samples in mixture comps table
- do not render structure editor & cas fast input for mixtures
- move component between tables
- option to merge components
- calculate total MW for mixtures & use in reaction table
- mixture samples in reactions scheme
- solvent volume column only for mixture samples
- add the preview image to component in mixtures
- modified the calculations related to various fields
- added the field for required total volume
- modified the structure of the solid components table
- import the molarity value from sample in drag-n-drop into component
- when Target Concentration is updated, then Amount and Volume gets recalculated
- re-calculate amount_mol and related attributes, when Purity is updated
- add the functionality to lock concentration for multiple components
- when there is Total Conc. and amount, then the total volume is calculated
- fix the amount_mol calculations to use the density or stock
- disable the lock concentration button, if it is 0
- lock the Ratio when total conc. is locked
- fix the tooltip buttons
- show indication in the sample list if the sample is a mixture
- split sample with components

fix (UI): cannot create a single molecule
fix: issue with the Amount field not being set for mixture components
fix: fetching of components after fetching the sample causing the sample appear as edited
fix: input fields CSS
fix: sample type selection input field

test: added test codes

refactor: code
refactor: eslint warnings
refactor: moved packs/src files to javascript directory
