Misc fixes

[rithvikvibhu]

A bunch of small fixes that don't really need individual PRs. Each commit is independent and only a few lines long.
There are a few more I'd like to add, opening this draft PR so the issues are linked on GitHub and it shows the icon in issues list.

This must be merged after #456 as that's where the base is branched off from.

auction: fix NaN HNS lockup value

(closes #396)
Max lockup from all bid values were not calculated properly and panel had NaN HNS lockup (pic in issue).

auction: replace p with div tag

React throws a large error when there's a div inside a p, so changed the p to a div.

auction: show open as pending only until it is

(closes #394)
All 6 hours of open period used to say "please wait while OPEN is mined". Now pending OPEN, and waiting for bidding start have different messages / button text.

domain-manager: hide names in reveal

(closes #378)
Names were listed in Domain Manager even if the reveal period hadn't ended and the wallet was currently the owner with the highest revealed bid. Now, those are hidden.

txs: update tx history on new blocks

(closes #205)
Transaction history automatically updates on new blocks. The "key" for react's loop over transactions needed to include the pending status, otherwise the transaction component wouldn't update and stays as pending.
There's also a debounce (of 5 secs) when refreshing transactions because it's a bit heavy and rescans / syncing a lot of blocks would parse all transactions each time.

watchlist: get list on node start

(closes #457)
regression: Watchlist wasn't loaded on start. Now it does on node start (as watchlists are network-specific).

i18n: extract more hard-coded strings

(closes #454)
Added more strings to locales json. More info in issue ^.
Note: These strings have been updated in english and will need to be translated again when #446 is merged: openSuccessText, getCoinAirdrop1

text: fix airdrop amount, libusb ver

(closes #425, closes #445)

• Updated airdrop amount
• Updated readme to specify libusb version required to build on linux

onboarding: disallow primary as wallet name

(closes #410)
primary is excluded from the wallet list that's used to check if a wallet with the same name exists when creating a new one. So handled it specifically.
This is related to (but does not close) #438 which seems like a better solution. Removing primary from all files will need a bigger commit in a separate PR.

ui: add settings icon on login page

(related to #182)
If an RPC connection is broken without any wallets, there's no way to get back to a working state:

If Bob switches to use an external hsd node instead of starting its own and it is not able to reach it, it says "no connection".
Unfortunately, the option to start the internal node is in the Settings page, but it can't be reached until a wallet exists. But it's not possible to create a wallet because there's no connection to a node.

To break this deadlock, allow opening Settings directly from the login page. Only Network & Connection section's direct actions (start/stop node, spv, dns) and custom RPC modal are allowed. Trying anything else goes back to login.

ui: do not set state if unmounted

In Account: setState was called after an await, that errored if the component was unmounted before the promise resolved. Now, it verifies that the component is still mounted before updating state.

throttle updateHNSPrice

The CoinGecko API was being called way more than needed (state updates in Portfolio, etc.)
Now it is throttled to 2 mins.

ui: no overflow for records

To fix #119, overflow was added to collapsibles, but it also affected Records in Domain Manager, where content should not overflow:

This is fixed.
